I am running TomatoVPN 1.25vpn3.4 on a few WRT54GL routers. I currently have them bridged together via a TAP interface. I have everything working properly right now except that I need to be able to limit access to the main network based on MAC address. The server router has an IP address of 192.168.1.1. The client routers are 192.168.1.90, 192.168.1.91 etc... and SHOULD only have one device connected to them that is allowed to access the main network (A Panasonic VOIP phone). Any tips on how to limit VPN traffic based on MAC addresses? I am hoping this can all be done at the main router, but I will take any suggestions on how to do this. Thanks in advance!
