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 have typed in /etc/rc.config.d/firewall2.rc.config this rule: iptables -A FORWARD -i eth1 -s 192.168.1.0/30 -j MASQUERADE Is this any problem with this rule? Because when the system is booting in process boot i get this line: Starting Firewall Initialization: (phase 3 of 3) iptables: Invalid Argument and only router system can see internet and another system can't see internet How can i solve this problem that another system (internal network) can see internet?
