Here is what I am trying to do: RV042 VPN into Cisco router - No problem works like a charm RV042 VPN passed Cisco Router into ISA 2006 Server - Kills me. Main Office: Cisco Router 1720 68.X.X.26 -.30 for external and 10.X.X.1 for Internal ISA Server 10.X.X.2 for external and 192.X.X.1 for internal Cisco Router is on 12.3 IOS which should allow for auto NAT Transversal I have configured the RV042 to connect to the public ip address of 68.X.X.30 which forwards onto 10.X.X.2 which is my ISA server. I need to be able to VPN into both networks from my branch office which is where the RV042 comes into play. How can I allow this to happen? Errors I am receiving are something about peer is wrong. The rv042 expects th 10.x.x.2 instead of the 68.x.x.30 thanks for your help.
