transparent bridging over VPN

[JJeremic]

I have a need to establish a secure tunnel between two sites by using two routers, or two PIX525 firewalls, or two VPN3030 concentrators; the equipment is not an issue. This connection should be functioning as a transparent bridge, so layer 2 traffic. I guess, it is like LAN-to-LAN model. However, I haven's seen any good articles and configuration examples for it. Can someone help, please.

Thank you.

Ok what you can do is simple, create a gre over ipsec between the two sites. Configure irb on the router and bridge all the traffic from the LAN to the GRE tunnel.

Watch out, the router may give a warning saying that the bridging over gre is supported but it will still accept the command. It works without any issue.
