I am running a server that is getting a link from an external organization which is connected via p to p vpn. i want my client computers to access the link and my client computers are connected to my server via ospf. I need a solution that allows traffic coming from my client computers to point to the link coming from the external server.

I used point to point VPN and I cannot connect to the remote server because i have many client computers that are resulting in IP conflicts at th main server from the external organization
