Configuring iptables is not for the faint of heart. More power to you if as a newbie, you're already at that stage. But you might consider downloading a package for configuring a firewall rather than trying to configure iptables yourself. I personally cannot recommend a package because I've been configuring my firewall manually since before there was iptables. There used to be something called ipchains that did something similar. But if you find a nice, easy to use package, let me know. I haven't messed with my firewall in ages and it could probably be improved. Actually, an explanation of what I do might be useful here. I have a shell script called firewall. What it does is clears the iptables rules and reloads them one at a time. So instead of typing in iptables commands to add rules, instead, I edit this script and re-run it. Then, when I'm satisfied that it does what I want, I run iptables-save, redirect the output to a file, and then when I restart nnetworking, I have it set up to restore the rules from that file. In debian, that last thing can be done by adding a line to /etc/networking/interfaces. In the eth0 section I have something like: POST-UP /sbin/iptables-restore /etc/networking/iptables.rules The beauty of this method is that if I mess up the firewall script, say I add a rule that locks me out, I can reboot and it automatically goes back to the old rules. ----- Original Message ----- From: "Christian" <christian08@xxxxxxxxxx> To: <speakup at braille.uwo.ca> Sent: Thursday, November 16, 2006 5:26 PM Subject: Re[2]: Question about iptables in Debian > Hi, > Thanks for that.
