Forums Connection Issues mIRC channel blocked by Peer Guardian

I'm trying to figure out the correct address(for mIRC) to enter into the Peer Guardian Allow list for a chat room(internetplays) I watch. I've tried the obvious, http://irc.internetplays.com which is the address of the server, but that doesn't work. Does anyone use Peer Guardian and know how to get a channel to work with it.

Thanks, John
