I have a question on Iptables. I have yet to even get it to install correctly. I've done it from src, deb's, and rpm's. None of them work right. modprobe: Can't locate module ip_tables iptables v1.2.1: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. So I need to load the module.. Ok, where is it? I even had a friend who tried to install this as well. He had this same problem. He never did find the module it wants..
