    I am working on creating a firewall to do load balancing between two or
    more LDAP servers. I am using Fedora Core 2 as my firewall with two
    physical NICs. I have tried several different combinations of rules,
    but I cannot get it to work correctly. Here is what is going wrong:

    LDAP request goes to
    Request is routed to interface on same network and destination address
    is correctly changed to a random system to be load balanced.
    Once there is an answer for LDAP, the answer goes directly to the
    requesting machine, not the firewall that routed it.

    I know this is a very easy problem to fix, but I apparently am losing my
    mind and cannot think.
