Mandrake as firewall

sihere · 01-04-2004, 05:50 PM

I have installed Mandrake 9.2 on a Duron 800 with 512Mb RAM to act as my firewall pc for the ADSL connection.
The installation runs well, asks for the Alcatel mgmt.o file, etc, etc and allow me to share my connection.
The problem is that only port 80 connections work from my Win XP machine (and any other), all SSL, NNTP, MAIL, etc, etc ones fail.
Can anyone give me some advice please???
Thanx

Besides the fact that I don't think mdk is a ggod choice for a dedicated machine, you need know what firewall you're using. Try "ls -d /etc/*wall" or browse your installed packages list for a firewall...

I personally use shorewall, I find it really easy to use and flexible

If you feel brave, you can setup iptables manually:

Looks like everything except 80 is blocked.

try man iptables

You may want to look at Firewall Builder for an easy to use and understand GUI for building your firewall rules. I agree with ac1980 on using mandrake as your firewall machine. I would use RH or FreeBSD or some of the distros made to be strictly a firewall.

Look at Watchdog for realtime firewall monitoring.
