A few days ago, my internet connection wasn't working properly and I had to reset my modem in order to get it to work. I think my ISP may have done some upgrades or something.

Now, I am unable to connect to a whole bunch of servers that I used to be able to. The message that I get is " Unable to connect to server (Connection timed out)" Most of these connect on port 6667. I know it is not my internet connection, as I can use IE and AIM. I was also able to connect to a server that opened on port 6665.

If my ISP has put up some sort of block, what needs to be done in order to get MIRC working again?

Using: MIRC 6.16
Windows 2000 Pro
Cable modem - Linksys
