Information about VPN

[Jesus Antonio Santos Giraldo]

Yep the tunnel thing.

A question:

Once a tunnel is established then the remote computer behaves as if were 
connected to the enterprise LAN isn't it?

So I can access a computer at my company with VNC?

Could I use FreeNX instead of VNC, once the tunnel get created?

Tnx.
