5 DCC Receive is no problem at all, because of the way DCC works (Someone offers
6 you a DCC send and sends you his IP an a port which _you_ connect to. The
7 offer goes through normal irc traffic so it comes through and the rest should
8 succeed unless your firewall blocks traffic to any ip on the port that the
9 dcc offer included.
11 If you want to send a dcc offer yourself this will of course not succeed as
12 you firewall will not let traffic through to the port from your dcc offer but
13 that's what the masquerrading modules is for (it's in the official kernel
14 tree for some time now). All you have to do, is insert that module before you
15 connect to the irc server (or compile it into your kernel).
