I want to know if there is a way tu put variables inside the /etc/sysconfig/iptables file...
I want to migrate my ipchains script (i have lots of variables) to an iptables file... not as script, but as the iptables config file itself.
Thank you

ipchains and iptables are quite different... you would be re-creating the sirewall rules....
its only a 2 minute job if you know how... and if u dont, get someone who does know or use an automated tool like firestarter.

It's also not advisable to manually edit the /etc/sysconfig/iptables file. The best way is to migrate your script to iptables format, then just run the script at boot or alternatively, you can run the script once and use the following command:

iptables-save > /etc/sysconfig/iptables

Sounds like your on a Redhat-ish system, so the rules should then get loaded automatically at boot by iptables-restore.
