    OK. You didn't mention whether this helped or made no difference. :-)

    Using FreeBSD as a router is a very common task: you generally don't
    need to tune anything to have it work pretty well, if the hardware
    underneath is OK. Can you confirm that you're not losing the
    connections because a NIC freaks out and drops the carrier, or
    something along those lines?

    What does top look like, and "netstat -m" and "netstat -i" look like
    during a lockup...? Anything in the logs or dmesg?
