that should be fine.  Depending on your desired routing, you may have
to use the WAN interface for one of the networks since it's the only
one that'll accept a default gateway.  If you do, you'll have to
disable NAT (see FAQ).  You may be able to get by without a default
gateway, and without a WAN interface.
