ipnat+ipfw + 3 gateways

[hugle]

hello all.
I'm trying to to smth like load balancing between 3 interfaces using
ipnat and ipfw

my gw's are:
213.252.192.161 on fxp0 with 213.252.192.162
213.252.192.141 on vlan0 with 213.252.192.142
212.59.9.1      on rl1 with 212.59.9.59


the ruleset i have is:
in ipfw:
ipfw add 1001 fwd 213.252.192.141 ip from 213.252.192.142 to any
ipfw add 1002 fwd 213.252.192.161 ip from 213.252.192.162 to any
ipfw add 1003 fwd 212.59.9.1 ip from 212.59.9.59 to any

and ipnat.rules
