Hello All, I have a linuxbox with 2 NICs working as firewall. I am using iptables-1.2.1a One NIC connected to Local lan and another nic is public ip address connected to router for DSL connection
I was behind this firewall machine I was not able to do MSN voice chat. I was able to connect and in another end who connected using dailup modem when they enable voice chat they get error as "there is problem in network or computer you are tring to connect" But in my end i did not get any error. I set rule as /sbin/iptables -A FORWARD -p all -s 184.184.1.3/255.255.255.255 -m mac --mac-source 00:50:fc:3d:98:6c -j ACCEPT /sbin/iptables -A FORWARD -p tcp --dport 80 -j DROP /sbin/iptables -A FORWARD -p tcp --dport 443 -j DROP /sbin/iptables -A FORWARD -p tcp --dport telnet -j DROP /sbin/iptables -A FORWARD -p tcp --dport 25 -j DROP /sbin/iptables -A FORWARD -p tcp --dport 110 -j DROP /sbin/iptables -A FORWARD -p tcp -s 0/0 --dport 21 -j DROP /sbin/iptables -A FORWARD -p tcp -d 0/0 --dport 20 -j DROP /sbin/iptables -A FORWARD -p icmp -d 0/0 --icmp-type ping -j DROP /sbin/iptables -t nat -A POSTROUTING -o eth2 -p all -d 0/0 -j MASQUERADE I thing this rules are aloowd to connect from machine behind it but it does not accept the connection from outside Could you help me to correct this rules.I tried lot of options but failed -Thanks Joe _________________________________________________________ Do You Yahoo!?
