I am trying to set a LAN-to-LAN connection my end ( 3745 router ) other end ( VPN Concentrator ).
For some reason we can't get the tunnel up.
We, from the 3745 router are making to the Concentrator, however that seems to be where the connection is failing. It has an error of " mismatch configured lan-lan proposal differs from negotiated proposal...
We have tore down the tunnels and rebuilt them, checked, and double checked the policies and the transform sets, yet they are still not coming uP??
Any ideas??
Thank you
