Wit ha bunch of caveats (you're using NAT, both lines terminate in the
FreeBSD server, you only care about outgoing traffic, the IP's you have
on both lines are in a nice contigious mini subnet, etc) you could
probably do somethign like this using IPF's ipnat:

map rl1 internal.ip.net.work/24 -> external.sub.net.block/30 portmap tcp/udp auto
