i tried to setup load balancing and nat on my own server.....
solution, presented here, lacks ability to balance connections from the
server itself.
so, finally i got my results on a such way:
nat from $myself to ! <local> -> { (vlan0), (vlan1) } round-robin
here nat balances entire traffic itself and this traffic originates from
kernel (squid socked), not passes through interfaces.......

i still need
pass out quick route-to (vlan0 $vlan1gw) from $vlan1me to ! <local>
to symmetric paths routing.

all other solutions with route-to weren't working for me (especially
combined with nat)

i hope you will hilite in your faq the difference between in-transit packets
and ones that
originated from the kernel/user_processes

p.s. my setup was accomplished on the FreeBSD, so, maybe "nat .... -> { ...
} round-robin"
       is FreeBSD-specific, i don't know
