My ISA server have this configuration: |VPN Server|-----|internet|------|ISA|-------|internal| My ISA have 2 network cards: External: 200.255.70.1 Internal: 192.168.10.1 I'm trying to estabilish a IPSec VPN using pre-shared key using the tutorial of Tiago de Aviz from ISAServer.org. After done, I cant stabilish the VPN. The network admin from "VPN Server" told me the fase I it's done, but wen will estabilish fase II, my server is sending the 200.255.70.1 IP. To estabilish fase II, my server must send the IP 10.21.90.145. Does n1 knows how I can do this? Thanks!
