Sorry for confusing you -- if it's a gateway, the OP needed to state
such.  I can't assume it's a gateway, because in this day and age people
try to do crazy things with networks, especially with bridging.

If it's a gateway, there's nothing strange about it.  If it isn't a
gateway, I can't see how any of the above would work.
