mIRC has its own fileserver, so mIRC acknowledges IRC can be used to share files... Not everyone has the intention to share pirated software, so I don't see why this question would be inappropriate in this forum. The fact I use Panzer is because it has much higher functionality than the mIRC fileserver.
Now for the ports: if it is a port problem, then why can I upload & download files? All ports are "open" when I SEND/GET files.
