I've got a VPN Conc 3000 series that is trying to establish a tunnel through to a 1760.
Both theses devices have other VPN tunnels that are working fine.
When we generate traffic the VPN tunnel comes up for 32 seconds before going down again, with no traffic going across the connection.
The remote site is using a public address range for its router and client machines.
VPN's from the client machines behind the router get through fine.
Pings from the concentrator don't get through to the remote router, however the tunnel phase 1 does seem to complete.
Im guessing that as the IP address range on the remote router is the same on its public as its internal that there is some routing conflict that is stopping traffic, can any one point me in the right direction please?
