This syntax is incorrect.  For some examples of multi-homed
configurations see the manual at

When you specify "networks" because you specify the interfaces to use,
you don't need to specify the ip address.  I think you are confusing the
networks and ipnets options.

What is the topology exactly?  Are there two nics or one nic with two
addresses?  Are the two nics on the same physical network or separate
physical networks?
