This thread has been taken out of context.   The real initial question
was whether or not you could bridge over the internet.  E.g., have 2
LANs that are Layer 2 Bridged over the internet.  Somewhat like DLSw+
can do for NetBIOS and SNA.   It would have the same effect as doing
this: (which you can't do)

int tunnel0
 tun sour 10.10.10.1
 tun dest 10.20.20.1
 bridge-group 1

int eth0
 bridge-group 1

Somehow IP would have to encapsulate the incoming MAC frame as the data
portion of the packet, and then release it as an ethernet frame on the
other end.
