Yes, round-robin will do. My problem is how to do this, I have tried
the following kiind of approach:

pass out on $ext_if route-to { ($ext_if1 $ext_gw1), ($ext_if2
$ext_gw2) } round-robin proto tcp from $myown to any flags S/SA
modulate state

However I can not, say, route-to $ext_gw2 traffic from $ext_ifi1's IP
address. I need to combine it with NAT, right?

How to do this is what I am confused.
