I have looked about a bit to try to find documentation that explains how the default firewall is set up .
I need to know where the config. files are, how to configure them etc. etc.
Actually, the reason why I wanted to know this was to switch the DARN THING off.
I normally write my own script, save it as "firewall" or something like that in the directory /etc/init.d/rc.d/
and add it to my run level.
The result of doing this was that the firewall was overwritten by whatever the gnome-firewall script does during boot up.
When I restarted my firewall, then everything (firewall and masq) worked fine, until I reboot again of course.
I treid disabling various services, but nothing made any difference, and I could not locate any documentation on the gnome-firewall, so I took to guessing at a few strategies instead (reminds me of win 95 at this point).
Anyway, to cut a long story short , I solved the problem by cutting and pasting the firewall script to the file /etc/rc.d/rc.local instead.
I'd like to know why the firewall didn't work before doing this.
Anyone got any ideas/info on this (useless) gnome-firewall so i can try to work out what was going on before I fixed the problem ?
