Setting up a Cisco lan-to-lan bridge

Fishing for ideas.

I'm wanting to set up a remote site on VPN. The remote office would have a small pix, like a 501, which would connect via lan-to-lan to a Cisco VPN concentrator (3000 series) at the other end. Now for the tricky part.

For various reasons I won't go into because they are not relevant, I want the remote office to be on the same /24 subnet as our production network. This remote office would contain only two servers, the pix, and a dsl router. Seems like it should be doable, but I haven't found a ready source of info on how to go about it. Part of the problem is that I keep postponing my PIX training!

Anyway, the remote office would have a 6mbps dsl line, static ip. The main site has a T1 going out.

So, the actual question: Is it possible, using the Cisco equipment noted above, to set up a lan-to-lan vpn connection as a trasparent bridge?

By the way, we do also have a pix 515 at the main site that is NOT currently being used for VPN.

No, it is not possible to bridge two Networks with VPN Site-To-Site. You only solution would be to get a direct line between the two sites, you can not do it with VPN.

Naveedb is correct if you were to setup a fiber connect or line of sight connection between the two sites it would be possible, but instead you will need to setup two subnets and route data back and forth over the site to site VPN

Thanks.  That's what I figured, given the dearth of information on the subject and what I know about vpn/pix already; I just hoped that some genius Expert out there knew of a way to do it. I had done it with a fiber bridge at my old job, but don't have that option in this scenario.
