I'd like to configure a VPN server inside a LAN without changing perimetral router configuration.
This should be possible using NAT-T, but I can't understand how does the router know the request has to be redirected to the VPN server, when a VPN client asks for a connection.
Could someone explain me how does NAT-Traversal work?
Thank you for your help.
