Folks:

I have a lab configuration where I've got traffic coming in on two 
Ethernet links into an OBSD 4.2 (GENERIC) box, with a third link 
connected to an Ethernet LAN where I'm using PF to do round-robin 
load-balancing to a small set of test web servers. The two incoming 
Ethernet links are simulating WAN links (no special equipment, just two 
links), and I'm wanting to make sure that traffic that comes in on 
"Link-A" goes back out on "Link-A".

The example in the man page wasn't so clear to me. Could someone here 
give me a definitive cookbook / answer? Does PF just "do this" while 
tracking the state of the connection, or do I need to specify a few 
rules to make sure things get routed properly? The two incoming links 
are an equal-cost routing path to the source network.

Many thanks to all in advance for any / all advice / tips / steers.
