iptables on the commandline

Hi,

Is there a way to run iptables on the command line to permanently add rules? I am able to add a rule through the command line but it does write to the /etc/sysconfig/iptables file and therefore if iptables is restarted then it will go away.

thanks
Andrew

iptables is not there to do anything permenantly. that's up to a service script. generally redhat recently added iptables as a service too (which is potentially confusing) you can normally run /etc/init.d/iptables save to pull the config out and commit to a startup file, which is probably really what you're after. this isn't actually iptables though, but redhat writing wrapper scripts.
