use ipfw and fwd command.
for example with output section
add 10000 fwd gw1_IP from DSL1_subnet to any via gw1_ethernet
add 10001 fwd gw2_IP from DSL2_subnet to any via gw2_ethernet
add 10002 fwd gw3_IP from DSL3_subnet to any via gw3_ethernet
please do treat above as an example of course.
Of course use right squid commands so it will select right source IP based
on the rules you want, but as you already did id under linux i assume you
have this practiced already.
i had 5+2 Polish Telecom links connected to one server - worked fine.
