iptables + guarddog problem


Hi everyone.

I have a little problem with those 2 programs.

Since firestarter got off the portage tree I decided to give guarddog a try. I set up all the needed rules for having internet as well as msn and irc connections open. The problem comes when I reboot the system.

Although I have a well setup kernel (2.6.18) and iptables loaded at init script, I can't get any connection out. It's not since I start again guarddog and apply again the rules that I have connection. So what I did was:

1.- Configure iptables through guarddog
2.- Save the rules
3.- iptables-save
4.- Reboot computer

No luck. It seems like iptables is not loading all the needed modules to let internet go through iptables. Only when I load again guarddog and apply again the rules it loads a few extra modules (I'm at work, can't remember exact modules) and then everything works like a charm.
Is quite annoying having to run eveytime guarddog just to hava the rules re-applied.

Any hint on solving this?

Thanks in advance

How do you know it is the modules that are failing to load?

Is this PC a gateway device? If so does Internet access from the gateway device and the PCs behind it not work?

Just curious...

What does step 3 do? I use Guarddog and have never had to do that command.

Guarddog save the rules as /etc/rc.firewall. If you need to stop or restart the rules there's two ways.

1. In Guarddog's interface, under Advanced, is a checkbox to disable the firewall. Check it off, Apply, check it back on, Apply again.
2. From the commandline:
/etc/rc.firewall stop
or /etc/rc.firewall restart

If #2 works you could add it to a startup script. You mentioned previously using another program. Could there be a script from it, similar to /etc/rc.firewall, somwhere that's conflicing?
