mIRC through proxies and firewalls

I had this problem a thousand times, it took me many hours to solve it in every single case, but there´s a really good guide available at the mIRC website how to manage this fast and easy :

And for all of you who aren´t lucky with this guide. If you have a linux box somewhere in the net to connect to, use xming and putty and just tunnel your way through the wall. Good luck !!!

proxycfg & netsh winhttp show proxy

Update:

If you use Windows 7 or above the proxycfg command won´t work. Instead you can you netsh with the following syntax:

C:\netsh winhttp show proxy

Howto find out the proxy configuration, if all IE security options are invisible and disabled ?

Good question and the answer took me 2 hours of search on the net. The answer is so damn simple, that I felt a bit annoyed after I found it:
