I have an Ubuntu 10.04 server to which I would like to connect remotely via VPN network.
The VPN works fine (using PPTP), but I still have some problems configuring the Remote Desktop application:
simply using System->Preferences->Remote Desktop allows me to connect from a Windows XP machine with TightVNC but not the Windows Remote Desktop application which I would like to use.
But most importantly, I have now a situation where I could connect via Remote Desktop (so far with TightVNC only) either using the VPN or not. I would like the Remote Desktop server to allow incoming connections ONLY from the private LAN (i.e. VPN network) and NOT from the public internet.
How do I achieve that?
Thanks for any help you can offer!
