WM6: Ok, VPN: Ok, Remote Desktop: NOT Ok - HELP

Hello all,
I have been successful in loading the WM6 ROM: works great! I have been successful at using the phone for Bluetooth DUN. I have been successfull at setting up a VPN connection to my place of employment: I can look at the RRAS server GUI and see that I have established a viable connection.
What I have NOT been successful at is getting Remote Desktop to work. RD is one of the reasons I upgraded to this ROM. Has any one been able to get their Windows desktop on their Treo? If so, how did you do it?
I can't seem to find any pertinent information on how to make this work so anything you can tell me would be a great help.
Cheers,
idyllic

Joannaex,
thank you for the forum pointers. Alas, they did not help. I did try to load the cab file from one of the threads, but it loaded the same version of Remote Desktop Mobile that I already had. I still get the same errors encountered with the previous version. Maybe this behavior is due to the "unofficial" ROM not being fully functional in some way? I don't know. It would be interesting to hear from someone that actually got this to work.
Cheers

PS: in occurs to me that this might be a routing issue in the 10.x.x.x/192.x.x.x space. I could verify this if there were a command prompt where I could run things like ipconfig, tracert, netstat, etc. Or a log file that could be viewed. Just wishful thoughts I suppose
PPS: Just found two great progs, one called VXIPCONFIG which give you the info you would get in you did an ipconfig /all. The other is called VXUTIL which you can do PING, TRACERT, WHOIS and a lot more. The utilities are available from http://www.cam.com/windowdsce.html.

I have been able to connect to remote desktop. What has been successful for me has been to already initiate my 3G connection then connect using remote desktop. It doesn't seem to be able to start up the connection itself.

andokia,
I am doing the exact same thing: starting my 3G connection, then my VPN connection, and lastly Remote Desktop Mobile. The RDN ALWAYS times out with one of these two errors: "Connection Status - Cannot Connect. Likely reasons are: 1. Specified computer name or IP does not exist, 2. A network error occurred while establishing a connection." So, I'm kind of at a loss here as the troubleshooting tools available are not great. Thank you for the response!

Hi idyllic,
Can you access a remote desktop when a VPN session isn't active? I have used the two separately without problems but haven't tried them together.

andokia,
no, I cannot access any system. I have tried my home system (firewalls turned off and on). I have tried my work systems (VPN on and off). Nothing seems to work. It's really frustrating to have a tool that you know can help you, but it doesn't work: aaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhh!

I'm assuming you're trying to use a local address because you are connecting with vpn first. Did you put the local address in the exceptions list? If not the vpn connection will disconnect anytime you try to use an address that is not in the exceptions list.
Exceptions list: start\settings\connections\connections\advanced\exceptions
then add the local url
Hope this helps. Used to be the problem I had when trying to use VPN.

chris44gw,
yes, I'm trying to connect to a local addres, but that address isn't a URL. The address I'm entering is an IP address of the machine for which I want to get a desktop. Now maybe I'm wrong, but my understanding is that I can use Remote Desktop Mobile to get, say, a desktop/console of one of my servers.
I've been able to surf the web on the phone, I've been able to use the phone as a Bluetooth modem, I've been able to connect to each of my companies VPN servers. Still now desktop. Whether I enter a fully qualified domain name or an IP address it never works.
Now, I have a little more information. If I just connect to the AT&T 3G network I can do a traceroute to the VPN servers. If I then connect to the VPN (PPTP connection verfied and active) I CANNOT ping anything on the corp. net. It has to be a routing issue I'm thinking. It seems that it needs to be fixed on the phone side, but I can't seem to figure out where to do this.
Anyway, I appreciate the pointer about the URL exception list.

That's what mine looks like. Once I'm connected vpn wise into my 2003 server I can RDP into it and another XP machine on the network through the local IP. Only thing I can think of is if you have activesync connecting to an exchange server. It might disconnect the vpn. I think you've said you're verifying the vpn connections so I might look into the firewall on the computer or make sure RDP is on for the computer (although you've probably done that). Good luck though.

chris44gw,
thank you for the screen-shot. I gave this a try, but no luck. We don't use exchange servers at work and I've verified that no active sync is active during the connect process. Having downloaded a couple of tools to help troubleshoot, I've noticed that I CANNOT ping anything on the internal network: this after verify that the VPN connection active and viable. I have also verified that each system that I am connecting to has RDP turned on. I guess I'll just keep experimenting. I just can't help but think that there is ONE LITTLE THING that is keeping this from working.

PS: What encryption level does the Treo 750 VPN app use? 56bit? 128?
PPS: Upon further testing... when I connect to the RRAS server (and connecting to the RRAS server has NEVER been the problem) on the West Coast (Windows 2000 Server std. SP4) I cannot ping the "inside" network. When I connect to the East coast RRAS server (Windows Server 2003 SP2) I CAN ping "inside" network. In either case I still cannot get a remote desktop.

Have the same problem on Diamond
Hi all,
After upgrading to wm6.1 on O2 Diamond unable connect to Remote Desktop.
When manually connected to Internet it works perfect, but from RD Client there is always an error (dial up or Proxy settings). All other programmes can always correctly initiate internet connection via GPRS/UMTS. Via Active sync RD works always.
MFG

Sorry, never got it to work. Call me a traitor, but I now have an iPhone and everything works the way I expect it... with two major exceptions: 1. no cut-and-paste, 2. can't be used as a tethered modem without jail-breaking the phone (which I'm not willing to do).

Similar problem HTC Touch HD
Hi all, sorry in advance if my problem ends up being because I've missed something basic; I'm trying to setup RDC on my HTC Touch HD with no luck. Computer name is right, password is right, IP is right. Fail message:
"connection status. cannot connect. likely reasons are: 1. specified computer name or ip does not exist. 2. A network error occurred while establishing the connection."
I'm connected to my WiFi network which also has the machine i'm trying to connect to on it. I've also tried when out of network range, connecting via 3G/HSDPA. Steps I've taken:
-Enabled remote desktop in system properties on target machine. Haven't added any remote users as it already allows me (admin on target machine) and I'm using those login details to access.
-Allowed RD in the packet settings of Kaspersky antivirus, using the address as the ip of my mobile, found by going to whatsmyip.com, and name as the name I've set on the device.
-Probably unrelatedly, I've also allowed the HTC to access the wifi through the MAC address access list
I can connect via a standard windows machine on the same router (which just needs the computer name, not the IP). Have found this useful as I had the details around the wrong way, but even now it's not working. Based on the tips in the link above, I'm under the impression that I should set things up thus:
Computer: the ip address of target machine
User name: EITHER my username OR MACHINENAME/User Name, e.g. John Smith OR JOHNSPC\John Smith
Password: pw
Domain: either machinename or blank.
Anyone know if this is right / which of the options for username and domain is right?

Help with internet sharing/tethering on Vista

OK so I thought I was halfway intelligent about all this but apparently not. I can't seem to get my internet sharing to allow me to tether on my new Tilt. I had it working fine on my Sprint Mogul so I know theoretically how to do it. I have the stock AT&T ROM (allowed customizations; just lazy about figuring out what I'd need of the customizations so I live with the bloat).
I created a shortcut for IntShrUI.exe in my \windows\start menu\programs folder to start the internet shar. I start Internet sharing and select USB and AT&T ISP GPRS (or MEdia Net; same result). It says connected and doesn't give me any errors but I can't seem to connect to anything from my PC or even ping anything. I'm using a Windows Vista PC. While internet sharing is connected I can connect to the web on the phone itself but not from the PC.
I was originally on "PDA Personal Max UNL + 1500 Messages" but I couldn't seem to connect to ISP.CINGULAR and I thought maybe that's why I couldn't tether (and I thought it'd probably prevent me from connecting to my corporate VPN). So I called in and the tech guy said that plan isn't provisioned for ISP.CINGULAR so he switched me to the "older" (his words) PDACnctUntlAdd which is the same price and includes ISP.CINGULAR but not 1500 messages. In hindsight I'm guessing that's not my problem (especially since it didn't fix it) and I'll prob go back to PDA Personal Max with the 1500 messages once I figure out the tethering and assuming it allows me to VPN.
My settings are:
AT&T ISP GPRS
Modem:
APN: isp.cingular
Username: [email protected]
Password: CINGULAR1 (doesn't show it but found that online)
Domain: blank
Advanced Settings:
TCP/IP: Use server-assigned IP Address
Use software compression: not checked
Use IP header compression: not checked
Servers: User server-assigned IP Address
Proxy Settings:
This network connects to the Internet: checked
This networks uses a proxy....: not checked
MEdia Net
Modem:
APN: wap.cingular
Username: [email protected]
Password: ????? (doesn't show it and never looked for online)
Domain: blank
Advanced Settings:
TCP/IP: Use server-assigned IP Address
Use software compression: not checked
Use IP header compression: not checked
Servers: User server-assigned IP Address
Proxy Settings:
This network connects to the Internet: checked
This networks uses a proxy....: not checked
I've tried to do it with the proxy disabled (running Disable Proxy from programs) and with it enabled with the same result.
So what can I be doing wrong? I'm sure it's something supremely stupid (if it's not a provisioning problem but how could it be that?) but I can't for the life of me figure out what I'm doing wrong.
Any help greatly appreciated and let me know if there's anything else you'd need to know to get this working.
If it matters I have the following installed:

So your device says connected (and can surf the web) but your laptop wont connect?
So is your laptops firewall blocking the network?
Have you tried it over bluetooth, and use the BT PAN option. Select BT in ICS and click connect, and click YES to allow it to be discoverable, then in Vista, click start, connect to, Then click Set up a network or connection. Then scroll down to the bottom option (BT PAN). Click it and it will offer your device's BT PAN, select that and click connect.
Wait for 30 seconds, then open the web.

Solution from ATT-Connect your Laptop/PDA
Here ya go! Tried it myself with the usb. Workin good-ATT has a comm manager app that installs on the laptop.
Here's the link to the ATT support for it.

Alemaker

Thanks for your help; hadn't thought of turning off firewall since it worked with the mogul without doing that. Tried that and it didn't work. Then tried with bluetooth and that didn't work either. Didn't want to use the ATT comm manager on the off chance that they could track tethering usage on it.
And of course it was a stupid thing not to check but something made me try connecting to an IP address and not a URL and BAM! it worked. So I guess I have a DNS problem and not a connection problem.
So now anyone have an idea why the laptop can't resolve DNS but the Tilt can? Should I manually set free public DNS servers on the Tilt? Or on the laptop?

Vista you said? correct?
Try making the network that Vista sees when you connect-private; if it's public,it'll block stuff

Yeah, it's already set to private. Still no DNS resolution. I'm going to try using a free public DNS server on the PC. Strange that the Tilt isn't passing thru DNS for me but it seems it is for everyone else.
Well using the free DNS servers (208.67.222.222 and 208.67.220.220) seems to work now and it even seems to resolve DNS faster. I feel better that I figured out how to get it to work but I'm definitely confused as to why it doesn't work by default like it does for everyone else.

get tethering working yet?
hi,
i have the same issue. have unlimited data plan on my tilt. no problem with connection on my tilt (although i did not put in all that proxy setting crap att asks you to put in).
anyhow
- installed the htc modem driver on my laptop.
- turned on the modem on the tilt
- created a new dialup connection on my xp laptop
---> question here, what is the "phone number" that should be dialed???
--> for [email protected], password is CINGULAR1 also
as a last resort i will try using the att comm manager, but like you i don't really want to do it due to any tracking att may be doing...
would be great to hear if loading that local dns resolves your problem, altho it seems kinda clugey (sp?)

lol-
ya'all kill me.
Anything at all,including data; going through any major network in the U.S., is tracked- period. Cell calls,data,internet connections, and even landline calls are ALL tracked in the U.S. now. Thanks to the current administration, EVERYTHING is tracked.
Alemaker

I meant tracked in terms of tethered vs non-tethered (not being on a tethered plan; but then I tether about once a month when travelling in airports if that so I'm not worried about it). I know big brother is always watching (especially on AT&T):
http://abcnews.go.com/Politics/Story?id=3833172&page=1
@jprai I did get tethering working by just changing my DNS settings on the laptop to free servers. I'm not using wireless modem but the Internet Sharing app on the PocketPC (go to \Windows and copy the shortcut "internet sharing.lnk" to your \Windows\Start Menu\Programs directory and then you'll be able to start the app easily). It's much easier to use (well now that the DNS issue was figured out).
I'm still very curious why DNS isn't working for me with the default settings and it does for everyone else but I'm OK with this work-around for the time being.

This did the trick for me, thanks!
For those not fully aware of how to do this, connect your phone with ICS, go to network connections (control panel->network and sharing center->manage network connections), right click on the phone's connection (hover over them if you're not sure about which is which... mine said NDIS something or other), go to properties, click on TCP/IPv4, go to properties, and then give it the DNS addresses listed above.
Thanks!

Kaiser and VPN

Hello,
does someone use a VPN software on the Kaiser ?
Wich one ?
I tried several but none worked.

My Kaiser is using the built in VPN client, to VPN into two different Microsoft RRAS networks using PPTP and IPSec/L2TP.
What problems are you experiencing? What type of networks are you trying to VPN into?

Thanks a lot for your answer !
I didn't know the Kaiser had a VPN client included ...
Where is the application ? What's its name ?
Is there a documentation I can find somewhere to help me to configure it ?
The other thing is that I use a SecurID password to connect to my corporate network, I don't know if this can work also with the Kaiser VPN.
In fact I would like to connect to my corporate network wich accepts both IPSec/UDP and IPSec/TCP. All I know is that I need a Cisco compatible VPN application.
I tried "AnthaVPN", it connects to our Cisco server, but then it disconnects after a few "Time Out" errors.
Thanks again for your help !

I would be interested in this too... we use Cisco at work using Cisco ipsec/udp but no idea how to set this up on the phone

Finally I've found how to use the buit in VPN, but it still does not work for me, because of the SecurID password I think (it says my login/password may be incorrect).
Here is how to access to the built in VPN (my device is french, I translate it to english but I'm not sure the names will be the same on english devices):
parameters/connections -> choose the "Connections" icon.
Then choose "Modify/Configure my VPN servers"
After you filled everything there, choose "Manage existing connections".
At the bottom of the screen, choose "VPN". The VPN connection you made should appear here.
Put your stylus on it until the options "delete" and "connect to" appears.
Select "connect to" and then you should be connected to your network.
I hope this helped.
So finally, I am still searching for a VPN application wich would work with SECURID passwords.
Does someone know one ?

Cisco VPN Help Required
Even my office uses a Cisco PIX Firewall with VPN. Even i have tried many softwares, but nothing seems to work. I thik it is because of the 2 phase authentication of the Cisco VPN.
Also just for info, we use IPSec over UDP (NAT/PAT)
How to set this up in my KAISER?

Hello to all
Im using AnthaVPN and it's work great with Cisco VPN Concentrator System in my KAISER. There must be also a way to connect to a pix.
http://forum.ppcwarez.org/viewtopic.php?f=41&t=32009&hilit=AnthaVPN
Greets
Haija

Like I said, I tried this one, but it did not work with SecurID keys.
I also had a problem with it related to the WIFI :
when I tried to use it with WIFI enabled, if I wanted then to disable the WIFI, it was impossible, even after a soft reset. I had to deinstall AnthaVPN to be able to disable the WIFI.
So finally I think the built-in VPN is better than AnthaVPN because I had no WIFI issue with it.

I have read the manual from the Homepage AnthaVPN and for me its OK. But i haven't testet over wifi. Over GPRS works great.

i'm using the Bluefire VPN CLient (www.bluefiresecurity.com) to connect to my university's vpn (cisco) and it's working great.
with AnthaVPN i was not able to disconnect wifi anymore (phone would hang up -> soft reset -> wifi on again), don't know if they fixed this till now

So I was not alone to have wifi problems with AnthaVPN !
Finally I tried Bluefire VPN, it works a lot better than AnthaVPN (no more wifi problems !), I can go upto the SecurID login, but after that, at "Phase 2", I have an error code talking about IPSec parameters...
So I still have problems but now I know that Bluefire is working with securid keys.

VPN connection (PPTP)

Hi there. Please anyone if has info on this:
Have you ever managed to connect through VPN and PPTP on a windows VPN server? And if yes HOW?
I have tried thousand of times to set My work network settings and nothing...
Thanks in advance
P.S. It seems it tries the connection, on the server side i CAN see the connection established but from the mobile side it seems to drop..

have also had problems gave up in the end but would love to get this working, anyone got a top three list of best VPN clients

SO... its a telephone company GAME.. another one!!!
They DONT let VPN passthough..!!!!!!! If someone wants to connect with VPN to his office/home needs another packet to activate (Cosmote Greece) which costs the same as the internet connection!!! They just want our money!!!
If i try this connection (VPN) through wireless internet works just fine!!!

[Q] VPN issues

Hi All,
I am having issues when trying to connect to my work VPN. I need VPN access in order to check my work email and browse an internal website.
Now, the VPN always connects, either on 3G (in UK) and wifi.
However, even if it says "connected", I am not able to download emails orbrowse the intranet unless when connected to my home wifi and sometimes on mobile internet.
If connected through other wifi networks (recently tried on a hotel free wifi, in the states and on a private home network, in Croatia), the connection itself seems to go through some sort of bottleneck, and no emails or browsing is then available.
I am blaming the phone itself, since my colleague had no problems whatsoever on his iPhone.
I am on Galaxy Note, non rooted, Vodafone UK.
Please help, this issue is making my Galaxy Note almost useless.

just FYI I'm also on UK Vodafone and I can connect fine with openVPN to my home network ... tested on 2G,3G/H+ and also on various public & private WiFi networks - always connects fine, only issue I have is that my server .ovpn tells the phone to use my home router as it's default gateway (so that I can browse securely on public wifi). This doesn't work out of the box - I need to use the openVPN app's "fix DNS" option.

errr ... I'm an android noob, but AFAIK you need root for openVPN to work? I never tried running openVPN on my note BEFORE I rooted it, but anything I've ever read says root is required?

What APN do you use?
I have to switch everytime to something called MyLan to connect over 3G.
I am using the stock VPN client, did not adventure myself into OpenVPN. Would that work with an encrypted VPN?

Ah, sorry - I somehow managed to read the thread title "[Q] VPN issues" as "OpenVPN issues" .. case of my eyes seeing what they wanted to rather than than what was actually there. You are of course right, the stock VPN options don't need root (and of course openVPN client will only work to talk to an openVPN server).
I did set up a PPTP server on my WinXP home machine and tested that with the note's inbuilt PPTP VPN client - it worked OK although I needed to turn off encryption, and I didn't do anything with it beyond just connecting as I was only dong it out of interest.
re. the APN - I don't actually know where to see that on the note (noob, as I said!) - when I do settings->wireless & network-> mobile networks, which claims to allow setting APN's, there is no info or settings re. the APN other than the "network mode" and "network operators" items, neither of which seem to show the APN used for vodafone data access.
Anyway, sorry for the bum steer, hope you get it sorted

Oh, never mind
Under mobile networks you have to go under Access Point Names, but most likely you will only have one APN, which is the regular from Vodafone.
So most likely is the encryption causing problems?

D'oh ... I thought that was a heading, didn't realise it was a clickable item! my APN is wap.vodafone.co.uk (APN type is "internet+mms").
IDK if encryption is anything to do with your issues ... I doubt it if you can consistantly connect from home wifi and sometimes from 3G - if encryption were the problem I'd imagine it would consistantly connect (or not) rather than be variable.
Maybe worth trying to ping your internal mail/intranet servers when connected and then talking to your work IT guys in case there are firewall/routing settings that you are somehow falling foul of?

Yes we are doing that, however that fact that iPhones can connect really makes me wonder!

Thread Moved To Q&A​
This is a question, and as such belongs in the Q&A Section​

there are lots of third party vpn tools and free available you can use those

Wilsonj,
Can you please suggest one third party vpn tools that works well on PPTP, with encryption?
I am not looking at OpenVPN, since it doesn't suit my needs.
Thanks!
