Hello listmembers, I build myself a firewall on a gateway Suse 9.1 server eth0 = DSL(WAN) eth1 = LAN net-lan = 192.168.0.1/24 On the LAN 3 Windowsclients are talking to Internet via a switch. I can use Microsoft's MSN(chat) but using a webcam wont work. Here's a part listings of my firewall MSN rules: echo "MSN Messenger..." iptables -t filter -A FORWARD -i $lan -o $wan -p tcp --dport 1863 -s $net_lan -j ACCEPT iptables -t filter -A FORWARD -i $wan -o $lan -p tcp --sport 1863 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t filter -A FORWARD -i $lan -o $wan -p tcp --dport 443 -s $net_lan -j ACCEPT iptables -t filter -A FORWARD -i $wan -o $lan -p tcp --sport 443 -m state --state ESTABLISHED,RELATED -d $net_lan -j ACCEPT Is a webcam using another TCP port? -- regards, Jan Rozema Kortenhoef-Holland linux@xxxxxxxxxxx
