I'd guess you could have both active at once if you creatively
played with your routing table. Maybe route to the router
through one interface and route to the rest of the subnet through
the other interface? That way you would have two addresses on the
same subnet and both would be usable at the same time.
Maybe something like:
route add -net 18.239.0.0 eth0 netmask 255.255.0.0 metric 1
route add -host 18.239.0.1 eth1 metric 0
route add default gw 18.239.0.1 metric 2
I haven't tested this so it may not work. You might have to play with
it a bit. The biggest problem may be with servers that need to
authenticate you and get confused with you living in two places.
