I took a quick look at the site at
http://www.analogx.com/contents/down...work/proxy.htm
They just may not support that protocol. It does not appear to be listed there. (I don't have enough background with Proxy prgs.)
I turned to a Unix counterpart (Squid) for a cheap and dirty compare. Did a quick search on "irc"
http://www.squid-cache.org/mail-arch...9704/0365.html
If the person answering this has got it right, even this full featured proxy prg. won't handle irc....
This could be an authentication thing. Sorry I can't help you more, but perhaps someone on one of the Win boards has more experience with win proxy servers.
