Firewalls.
There are a number of posts on firewalls. Do a search on firewall and you will find some.
I think what you want is IPCop, Guarddog or Firestarter. Look at them and decide what one would be best for you. IPcop runs on its own standalone. Guarddog is just a front end to the Iptables which is probably what you want. The URL is http://freshmeat.net/redir/guarddog/...epage/guarddog Good Luck |

Go to www.linuxguruz.com/iptables
There are several scripts available to download. Just start downloading any that seem like what you want. Put them in /etc/rc.d/rc.firewall and make them executable. Try the one called Projectfiles.com Linux Firewall. It is extremely easy to configure. <edit> The best way to learn iptables (imo) is to start looking through these scripts and reading the comments. |
hi there,
goto http://linux-firewall-tools.com/firewall/index.html this is a let me hold your hand, answer the questions and when done will write you a script based on either IPCahins or IPtables. Ie used it and in about 20 minutes got a script done. ps I am an extreme novice on iptables and firewalls. but try it and see, give me a shout as to your thoughts. dave. |
