My current configuration consists of multiple router/clients connecting to a single server and the server routing traffic back to all clients. My problem is that the client side is not managed by me so the IP Address is often a duplicate of an already existing client. [url=http://postimage.org/image/42w4pz77f/][img]http://s17.postimage.org/42w4pz77f/Openvpn.jpg[/img][/url] I want to NAT at the TUN0 on each of the clients so that no matter how many of the clients are on identical networks they will route. Before I set this up in a lab I wanted to see if anyone has experience with this and can give me some input. Thank you, Peter

I really recomend you avoiding this collision. However, if VPN clients are on linux based system, you can use iptables' NETMASK option to get your goal.

the VPN clients are on ALIX boxes running Voyage Linux.
