PF load balancing

Hi,

I have two internet connections and would like to load balance outgoing
trafic between the two interfaces.

Using rules from the PF FAQ does not work for me (trafic is always
routed to the first interface).

The connections are both from the same provider, have a different
public IP address, but an identical gateway... Can this be the problem ?
