We currently have a setup with the AT&T modem in bridge mode, which goes to a Linksys 4-Port Gigabit Security Router with VPN modem that has the PPPoE information configured. Behind that we have another Linksys router with a different network address scheme that we want to access the Internet but use a different public IP address than the network directly behind the VPN router. We have a static IP address with AT&T with 6 addresses that aren't being used. I was thinking maybe we could do something with NAT to make it happen, but I don't see any configuration options for NAT that would allow me to do something like that. Another alternative I was considering was putting a switch behind the modem and putting two seperate routers directly behind that, but I don't see a way to do a static WAN IP with a PPPoE configuration. Any other suggestions will be greatly appreciated, basically the main objective is to just get both networks online but using seperate public IP addresses and only one modem.
