I have an IPCOP 1.4.21 firewall set up and want to block most of the world. I ONLY need allow incoming traffic from certain countries.
I have found several websites that give me a list of IPs for the countries but how do I block them?
I assume I need to manually build a large IPTABLE file but I have never done this. I did do a search on this web site and found several listings with internal workstation restrictions but nothing blocking traffic on the RED interface before it gets to my server.
