Bridge same subnet over VPN

I know this has been asked before but I have still to work out a solution.

Does anyone know how to bridge 2 identical internal subnets via a Cisco ASA site to site VPN.

10.101.1.0 is the subnet at both sides of the VPN and I am currently achieving this using OpenVPN but would prefer to use the ASA.

I believe it is possible using GRE tunnels.

If anyone has any ideas please help!!

Re: Bridge same subnet over VPN

The ASA cannot terminate GRE tunnels. You can use NAT to make both sides communicate but you can't extend the VLANs via a site-2-site VPN.

This kind of stuff is achieved with GRE,MPLS, L2TPV3 etc.
