Load-balancing

[Gilberto Villani Brito]

Hi,
I would make load-balancing using ipfw, but I have 2 routers in the same interface:

FreeBSD (200.xxx.xxx.3) -------> GW1 (200.xxx.xxx.1) (63%)
                            |--> GW2 (200.xxx.xxx.2) (33%)

How can I make load-balancing using ipfw???

I'm using pf (pass out on em0 route-to (em0 200.xxx.xxx.2) round-robin from any to any keep state probability 33%), but I would like use just one firewall.
