[nitjend]

Have to add user defined ports
I followed the below steps and added the port

System->Administration->firewall-> enable->otherports->add->userdefined

my query is that in which file, the user defined port get updated?

for example, all the existing ports will be available in /etc/protocols, like that the port which i have added will be upadted in which file?

Anyone please help on this?

Hi Nitjend,
With Fedora and Redhat, the saved data goes into:
/etc/sysconfig/iptables
for ipv4 and
/etc/sysconfig/ip6tables
for ipv6. Its probably different for Ubuntu.

In these files is raw iptables commands which is what configures most of your firewall.
