The majority of home firewall users need to keep mIRC's firewall option set to none. no, that doesnt mean the firewall isnt still working, it just means the firewall type isnt socks4, socks5, proxy type firewalls. If yours is, try this web page

i cant help but wonder if the ip/password you are referring to is to tweak settings at your ip level rather than the type of firewall i refered to above.
