    One thing that will keep an IRC connection from being established is if
    your proxy silently drops AUTH/identd requests on 113/TCP. The proxy
    doesn't have to run an identd daemon, but it does have to at least
    reject incoming AUTH requests with a TCP reset, instead of just dropping
    them. The IRC server will send these requests and wait for them forever
    if it never gets a response.

    I recently was finally able to connect to IRC servers by changing my
    firewall policy from DROP to REJECT for requests on 113/TCP.

    If your proxy admins are agreeable to you using IRC, you could ask them
    about it.

    Good luck,
    Andrew.
