Well, I don't think changing the DCC ports is something wrong:
Go to:
Tools-> Options -> Connect -> Options
Click on the Advanced button, check the DCC box,
change your first port to anything you want (20 maybe),
change your last port to anything you want as well (80 might work),
click the Randomize ports box.
There... different ports for DCC!
Why no one else would say this... censorship!
