All sorts. It effictivly maps your ip connections to the external interface of the ISA server. Without it your pc will think its ip is 192.168.x.x (or whatever) so when you DCC it tells the remote computer to connect to that ip address - which of course it cant as it's a non-routable internal only ip address (apart from the fact you are behind a firewall). With the firewall client when you DCC from mirc it replaces your pcs ip address with the correct external ip and tells isa to open the appropriate port - hence the remote pc can make the connection to your pc through the firewall. That's not exactly how it works im sure some will correct me on the proper facts - but its just the general idea.
