Hello, I've been looking for some information but couldn't find, so here it goes, I'm asking to the list : (excuse my technical english if I'm not clear enough) I've a LAN at home with mdk as server and win and mdk on the clients My question is : is there a way to block certain applications, such as specific softwares (office suite for example), to access internet with iptables? How to identify the packets emitted from such applications and block them ? Thanks Bruno
