Hello all, I'm using linux with iptables as firewall machine with two nic's. I've two windows m/c. One is behind the firewall and other is outside the firewall. I'm using MSN messenger in both the machines. My lan n/w is 192.168.1.0/24(eth0 192.168.1.24) and internet iface has ip address 172.16.1.111 which is connected to router. A windows m/c which is behind the firewall has ip address 192.168.1.135 & windows m/c outside the firewall has ip address is 172.16.1.100. I've set the below rules in the firewall m/c.
/sbin/iptables -A FORWARD -o eth0 -p all -s 192.168.1.135/255.255.255.255 -j ACCEPT /sbin/iptables -t nat -A POSTROUTING -o eth0 -p all -d 0/0 -j SNAT --to 172.16.1.111 I'm getting error in msn messenger from the m/c outside the firewall as "The network or computer you are trying to reach is experiencing a problem. Please try again later." I think it is not forwarding the pkts back to the 192.168.1.135. Is ther any other rule to add to overcome this problem. Thanks & Regards, -shadha _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
