Sorry it took so long: Below is the squid.conf followed by the tcpdump of the XP box attempting transparent proxy. Last is the XP box trying to go directly to the proxy port. Both are not working. However. If I dialup with my Gentoo Linux, both proxy direct and transparent proxy works fine with lynx, konqueror and mozilla.
Thanks for the help!!!
