Entering "iptables-save" before rebooting doesn't work; "iptables-save -c" as it says in the "Red Hat Linux Bible" doesn't work either. What's the right command here, in FC4?
Thanks again for the help. Jerry
You have choices. First of all iptables-save does work, but it writes by default to stdout, not to /etc/sysconfig/iptables which is the rule file loaded by the iptables service upon startup. So you could redirect output from the command to that file: 'iptables-save >/etc/sysconfig/iptables'
Second you could tell the iptables service script to save it for you: 'service iptables save'
Or third, you could edit /etc/sysconfig/iptables yourself to insert the lines # Permit access to slimserver -A RH-Firewall-1-INPUT -s 192.168.1.0/24 -p udp --dport 9000 -j ACCEPT
right below the line: -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
The latter method will preserve comments in that file, while the first two methods will destroy them.
