Why not just configure the two ports on separate subnets and enable IP
forwarding?
# routeadm -e ipv4-forwarding -u
That seems like the simplest possible answer. If you really want
iptables-like difficulty in this test, you could use the equivalent
functionality in IP Filter -- the "to" keyword should do what you're
asking.
