Im trying to use sockets from mirc at work, but my work uses a proxy to browse.
My firefox shows:

Manual Proxy Configuration:
Proxy: blah.blah.com
Port: 83
(use this proxy server for all protocols)

How can I get my sockets to work through mirc with a proxy?
I tried going to the firewall settings in mirc options and enter the same hostname and port, but it still doesnt work.
