contivity vpn client behind router with easy server
Hi, I've seen this argument before, but without an effective solution.
I have a contivity client behind a 857 cisco router. This client needs to connect to a remote VPN server.
With NAT enable and easy VPN server disable all works fine.
When I enable easy VPN server on the 857 (I need to connect several dial-up cisco vpn client from outside to this office) the contivity client can't connect anymore to the remote vpn server and hang up with the famous "bannet text" error.
I think that because the external interface of the 857 is waiting for cisco vpn client to connect, it intercepts also the data from the remote contivity vpn server, not forwarding to the client inside the LAN.
If there is a way to "passthrough" the contivity connection data to the internal client it would be very nice.
