What you want is an encrypted bridge. You CAN create a point to point
IPSEC tunnel, and then (if they are two linux boxes) use the bridge code
to create a VLAN that joins the two networks, but that is way beyond me.
The IPSEC is easy enough to set up, setting up the VLAN config is
tricky, and I don't remember how to do it anymore. I would find a Linux
bridge mailing list and ask.

Sorry I can't be more help...
