A friend of mine pointed me in the direction of this software that will allow you to share out your Internet connection more reliably and faster than Window's ICS. After two days battling with the software I finally emerged as the victor with a working router/firewall. Some of the things I have noticed that work (that didn't through ICS) are that I can receive and send IRC DCC file transfers, ICQ transfers now work again and a noticeable difference using the internet in general.
