I want to use suse 7.3 for router & i want to do masquerading. I have 2 net card that one is for internal network & another is for external network. eth0 for internal network eth1 for external network I was setting in /etc/rc.config.d/firewall2.rc.config (The options that related to masquerading) and type this command in command line iptables -t nat -A POSTROUTING -j MASQUERADE -o eth1 Is this any problem with this rule or in my configuration file? Because only router system can see internet and another systems can't see internet How can i solve this problem that another systems (internal network) can see internet?
