Dear List, How are you. I am a newbie to iptables @.@, so I need some help with my project... Right now, I have a VoIP server, that can record legitimate users, and would send the update of "legitimate user list" to a linux firewall, through an UDP socket. When a new user comes in, the server will send a "add user" notification. The legitimate user entries have expiry, when a user expires, the server would also send a "remove user" notice to the firewall. I want to modify the firewall, so the firewall can update its iptables rules, according to these notifications. Could you please give me some suggestions on how to make this happen? Your help will be greatly appreciated! Thank you very much.
