VPN NAT Problem (Traffic between Internal and VPN fail)
I have been fighting this for a couple of days now, and I just have not been able to figure it out. I am pretty sure that it is a NAT problem, but I'm lost at this point.
I have an internal network (172.23.45.x) and a VPN network (172.23.46.x) and I cannot get traffic to flow between the two. I was able to get NAT working so much that I no longer show errors in the logs about a Reverse Path Failure or a Failed to locate Egress traffic, but I sitll cannot get the two networks to communicate.
I inactivated the two old NAT commands and added in your nat command, but it still did not work. But I am still unable to connect from my VPN to internal services (PING or SSH). I am also unable to ping from my Internal to my VPN.
