1.) Go into mIRC options

2.) Open DCC/Options, and edit the port range (unless you want to forward
all of them :/)

3.) http into your Router (ie, http://192.168.0.1 ) and find port redirection. Add the same range you listed in mIRC DCC Options. *duh* Forward to your local IP (if you don’t know what your local IP is, open up a command prompt (start menu/run “cmd”), and type ipconfig

And stop being a tard, whinging about people “not accepting the DCC transfer”… the problem is YOUR end.
