Justin,

I have a client who has some legacy gear at a remote site that needs to talk to other gear back at their main office. Trick is, that the gear is legacy enough that it has no concept of a default gateway, so all of the legacy pieces need to be or functionally appear to be in the same subnet.

The traffic between the sites needs to be encrypted, but since some of the IP space on both ends would appear to be on te same subnet, getting IPSEC to work would be problematic.

If I had routers at both locations, I could probably do this with an L2TPv3 pseudowire, but there's a PIX involved, and I don't think it knows L2TPv3 well enough to be able to let me pass a pseudowire through...


L2TPv3 over IP uses ip protocol 115 (which can be changed with "ip protocol X" under the pseudowire-class), so i don't think there should any problem with PIX recognizing it.
Am i missing anything?

MPLS would be nice too, but that's not an option in this design.

Has anyone here tackled something like this before?
