               and more clients ...                             


I need load balancing outgoing traffic from:
192.168.0.0/24 ( NAT )
and 64.XX.XX.0/24, 65.XX.XX.0/24

It is possible to make this balancing with the PF ? Exists some software 
that I make this ? Zebra can help me?
This type of balancing gives to problems with the navigation of the user 
of NAT or IP valid ?
If it is possible, wanted to see examples with rules.

Thanks,
