my configuration is the following:
1 server windows 2000 with a sigle NIC, 2 ip numbers (192.168.1.4 and 22.214.171.124) actually the default gateway is 126.96.36.199 and the secondary gateway is 192.168.1.1.
188.8.131.52 is a firewall without natting and it is public
192.168.1.1 is a firewall with NAT to a public address (different carrier)
My problem is to correct answer back to a request coming from one carrier or from the other.
For example, if a vpn connection is coming throu 184.108.40.206 the answer goes back to itself and if a vpn request coming from 192.168.1.1 the answer goes back to 192.168.1.1.
For the fixed ip addresses of users i haven't problems using static routing, but, often i don't know this addresses becouse they use diaulp connections.
May somebody help me??
