Problems with IRC code

["Michael A. Nunes" <p@pcmike.net>]

Background: I currently do NOT build my kernel with any modules, as my linux
box is only used as a firewall/router.  I have no need to be able to
dynamically load/unload parts of the kernel.  Therefore, I build all
netfilter code directly into my kernel.

Problem: Up until 2.4.20 it has always been possible for me to hard-code
ports into ip_conntrack_irc.c and ip_nat_irc.c by simply adding the
following:

if (ports[0] == 0) {
                ports[0] = 4646;
                ports[1] = 5190;
                ports[2] = 5554;
                ports[3] = 6667;
                ports[4] = 6868;
                ports[5] = 7000;

in the respect parts of either file.  Like I said, this has ALWAYS worked up
until 2.4.20.  DCCs in/out on any ports in the above list would always work.
With 2.4.20 after adding the above the only thing that works is DCCs IN!
DCCs going out from a NAT'd box no longer make it through!

Question: What in the IRC code has changed so drastically that
I can no longer use the above method for "hard-coding" ports?
