Hi Sato,

Yes, You can build a simple load balancer with the the "forwarding" feature
of IPFW3.

In below example:
ipfw3 add forward, round-robin icmp
the ICMP packets to or, if you are trying to ping, then you need to ensure you packets can still reach after
it has been forwarded to the or 1.2   And the also ensure the
reason traffic can be routed back to your source machine.
