how do I allow specific ip addresses for xx port using iptables?

Good day experts

I currently have a Websphere Application Server running on Linux SLES 10 SP2, I access the administrative console through port 9060. Although I have enabled security to access the admin console, I would also like to filter access by allowing only certain ip addresses through that port.

Would someone guide me how to accomplish this through iptables? I've already read some docs about iptables and how rules/chains/targets work but I'm still new with this command

Thanks in advance

edit /etc/sysconfig/SuSEfirewall2

find FW_SERVICES_ACCEPT_EXT, and add something like:

the restart firewall:
/etc/init.d/SuSEfirewall2_setup restart

On Redhat/Centos, the iptables configuration file is  /etc/sysconfig/iptables.

On Suse Linux, it's /etc/sysconfig/SuSEfirewall2. My understanding is susefirewall is a wrapped iptabes ( it will generate iptables rules for you, and it's easier to configure).

you can still run iptables command from console/terminal, but the setting will be gone after you restart machine/Susefirewall.  If you want to use iptables format configuration like /etc/sysconfig/iptables, you have to disable SuSEfirewall2 and setup iptable initial script by yourself.
