Hi there, i'd like to know if there's a way to change mirc local source port. For example:

TCP Henry:3543 irc.caltanet.it:6664 ESTABLISHED

here I connect to the irc server irc.caltanet.it on port 6664, but the source port on my pc (Henry) is 3543. Can I change in any way this port? It would be useful to use mirc at work, where a firewall piss me off :P

Thank you very much
