We're trying to use your router to create an IPSEC\\IKE VPN tunnel with an external client but have encountered a problem: Our LAN is an 10.34.10.0/24 Class C but the resources on the network we need to connect to is a 10.0.0.0/11 Class A range. The network administrators of the other LAN have given us their public IP gateway address and have been assigned an encryption domain in the
172.20.44.0/28 Class C range, we have consequently reserved a range of 14 addresses (10.34.10.33-46) to match it. Our problem is that we are unable to convert our inside LAN range to the outside encryption domain range of the other network. The IKE negotiating starts but ends abruptly, caused by invalid requests from host in the 10.* range instead of the required 172.*. We have can't alter our network infrastructure for various reasons and the adsl\\router is currently used in SUA mode for the internal LAN. What specification must the router have to solve this problem as the one listed below can't do it.Any help would be appreciated Ciao
