I've been setting up my firewall rules but it's mainly to block out obvious bad folk that I don't want visiting (like Baidu constantly having 60 spiders crawling throughout the day..anyway). I'm just wondering what do most people do for protecting a webserver using firewalls? I'm using iptables to config my firewalls. It's just a personal server only used for websites like XenForo so I don't need anything else really. Any advice?
