haven't used it as strictly a load-balance option but you should be

use the normal load-balance features of PF as the connections go
outbound. Check this thread at

I suspect that won't NAT either and you would end up with packets
leaving the external interface with internal addresses. Please let us
know if you try it! It seems to use the tcp_outgoing_address you
would
have to ensure the IP address selected matched the outbound interface,
but then how do you load balance?
I think the idea was that after it was sent to squid and sent to an
internal address, you would then NAT it as if it were any old incoming
connection and load-balance it through normal outbound balancing
mechanisms. Whether or not it would treat the traffic coming out of
squid as inbound on int_if is an unknown (to me) but if it did, then
you should be able to just round-robin it normally
