Hi, As I don't wan't my wireless clients to use filesharing software I enabled the "Block services" filter without any luck (I still see the connections via syslog). So I used the rc_startup and rc_firewall scripts to get the newes patterns an insert them into iptables. Still no luck So - is it possible to block programs like Kazaa, Gnutella and so on and if yes - how ? Thanks for your help. [Edit] All "filesharing clients" are connected through a second wrt54g using WDS. -> Should the filtering also be done on this second router? -> Is there something differnt in this case with a wds network?
