IRC Client Chaos

I'm pulling my hair out trying to get my IRC clients to work on my Leopard.

None of them seem to be connecting to any servers at all.
I can boot into XP and access mIRC on my same iMac, so I figure its not my router blocking the ports.

Am I missing something here? How can I check and see if OS X is blocking my IRC traffic? What port numbers are you using?

What IRC clients are you running under OSX that you are having issues with?

I figured it out. I had to put in the range of port numbers instead of the defaulted ones left in the clients. It works now...

I know this thread is years old, however I am currently facing this same issue! It's absolutely driving me insane!
The user below you said they resolved the issue by changing the default ports to a range in the client he was using so I assume he set 6667-7000
however not much more information was given. To answer your question its ANY IRC client. I can connect fine on my phone through WiFi so I know it can't be my internet or my router. On top of this, I have tried with not only my iMAC but my iPad 3 and my iPad Air. NOTHING works!
The clients I'm trying are XCHAT Azure and LimeChat.
PLEASE help me resolve this issue It's very upsetting!
P.S. If you must know I'm using Yosemite.
