i use guarddog to make iptables [at least on my other box] but it says it can't find the firewall command and asks if iptables is installed. i use gentoo and i emerged iptables so it's installed... the error i get when i do an 'iptables -L' is as follows:
iptables v1.2.11: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
i'm using the latest kernel... 2.6.9-gentoo-r4
Oh and also, I use a router as a hardware firewall, is iptables still neccessary?...
