I have an 1841 as my public facing router.
Inside the network are multiple subnets.
Two of those subnets have server infrastructure for two separate companies.
One currently has a PPTP connection setup using Windows RRAS with the necessary port forwarding on the 1841 for PPTP and GRE.
I would like to setup RRAS on a server for the other company but I cannot see how I can port forward that PPTP and GRE traffic to the new RRAS server.
Unless I can setup port forwarding based on DNS name and not solely on IP.
Would an additional public facing IP work? If so, how would I set that up on the 1841?
Any info appreciated.
