Remote Desktop Over VPN

Asked by Chewmanfoo

Hello,

I managed to set up a VPN connection and connect to our school's VPN server successfully, but I can't go anywhere from there. I've read numerous articles on the Ubuntu forms about this problem, and I understand that it might have something to do with routing, but I haven't been able to figure it out.

I want to use the Terminal Server Client to connect to my office PC, which has an address of 172.16.1.39. I've made an exception in Firestarter to allow all communication to and from our VPN server's IP address at work. Can anyone give me a hand?

Hi Markus,

Thanks for the reply. I'll try an answer your questions as best I can:

1. I installed the network-manager-pptp and pptp-linux packages via Synaptic Package Manager and used Network Manager to create and configure the VPN connection. I was able to connect to the VPN server at the office successfully, but couldn't access my office PC through the tunnel. So, I installed pptpconfig and used it to reconfigure the VPN connection. Again, I was able to connect to the VPN server successfully, but couldn't access my office PC.

2. No, I can't ping my office PC or any other PC at work

3. While it doesn't run terminal services, I've configured my office PC, a Windows XP Pro workstation, to accept Remote Desktop connections.

When I had Windows installed on my home PC, all I had to do was create a VPN connection, point it to the public IP address of our VPN server, establish a connection, then use the remote desktop client to connect to my office PC's private IP address through the tunnel.

Allright.

Please export your settings to a pcf file, open it in a text editor, replace critical data with a placeholder and post it here.

Hi,

I had similar problem but got the solution .....

Problem:
1. able to connect to VPN
2. Not able to ping to any of the machines at my workplace from my home.
3. Not able to connect through RDP.(remote desktop)

Observation:
Network problem was preventing this since no reply to ping, however DNS resolution was OK since I was getting machine name resolved. My machine is windows xp and internet connection was working fine thru my LAN adapter. (PPPoE connection thru cablenet) Firewall settings were OK and nothing was blocked over there as far as my ofice applications were concerned.

Solution:
I simply removed one of the IP addresses from my LAN adapter. Removed default gateways and left that setting blank. Everything started working fine !!!! Ping also possible now.

Regards,

Thanks for the suggestion. I apologize if this next question is too "noob"... but how exactly do you remove an IP address from the LAN adapter? And which adapter? ath0? eth0? How do you remove gateways?

Thanks

Removing LAN address for WindowsXP is simple...

Just right click on local area connection near system clock in the taskbar and change the properties.

I dont know about Unix systems though.

does anyone have a solution for this? i'm in the same boat!

dns works as i can see the correct addr, can browse corp webpages, but no ping to machine (might be firewalled, not sure), but definitely no rdp. Same path works via xp / vista. Client machine is xp if that helps.

thanks,
Hypo

I have always had an issue connecting to my work xp desktop. I connect to my network via VPN, if I use a wireless conection I can not RDP to my desktop, it does work if I use a Wired connection.

My work arround for this was to install Firestarter (firewall front end) and turn off my firewall, everything worked fine then.

I have tried configuring my firewall and opening the ports that rdp uses but notheing seemed to work so I am stuck with my solution. I am sure there is a way to configure it to work properly.

Hope this helps you to get going.

Chris.
