Why not?
map if0 192.168.100.0/24 -> 192.0.2.10/32 portmap tcp/udp auto
map if0 192.168.100.0/24 -> 192.0.2.10/32
bimap if0 192.168.100.1/32 -> 192.0.2.10/32
map if0 172.16.0.0/16 -> 192.0.2.12/32 portmap tcp/udp auto
map if0 172.16.0.0/16 -> 192.0.2.12/32
bimap if0 172.16.0.1/32 -> 192.0.2.12/32
All of the outgoing from the 192.168.100.0/24 block gets translated to
192.0.2.10. All of the incoming to 192.0.2.10 not associated with an
existing connection gets passed to 192.168.100.1. The same thing goes
for the 172.16.0.0/16 block except it gets translated to
192.0.2.12. Isn't that what you wanted?
