iptables - advanced port blocking/stealth mode
I used to use ipchains (2.2.x kernel) and had ip masq rules setup (for sharing my cable modem onto my lan). I then upgraded to the latest Slackware version (8 i think) and installed kernel 2.4.x and then noticed i needed to use iptables.
I have iptables setup to do basic ipmasq, but I haven't been able to find any info of howto secure it (i.e. get all my crappy ports reporting stealth on steve gibsons shields up site). Does anyone have/know of any info on iptables configuration???
