It explains a bit more as to whats going on. In brief, if the firewall is turned off, then the inet connections become inoperable. When it is turned on things work. Thats a feature and "not" a bug. If this is a workstation behind an already configured firewall, then just allow everything. If not, then you'll have to configure some sort of rudamentary firewall. If you've got no services running other then maybe ssh to this machine, then when you turn the firewall on open the ports for the service you're running. Thats really all there is to it. I would suggest reading up on IP Tables a bit so you've got some idea of whats going on as opposed to relying solely a GUI config wizard. If you can find the packages try installing Bastille on your system. Its probably the easiest out there to configure, and once its done you just let it alone. -- Mark "If you have found a very wise man, then you've found a man that at one time was an idiot and lived long enough to learn from his own stupidity."

If there's aren't any services being run on this machine then it doesn't matter. The firewall has to be at least enabled in some fashion in order for the inet connections to function correctly. Which is why the poster notices functionality when the firewall is turned on, and no functionality when the firewall is turned off. By far the easiest and least troublesome firewall app I've seen and have been using now since Mandrake 8.2 is Bastille. I've seen Shorewall, and a bunch of the others; and have in fact tried them out. I always came back to Bastille. It just works. -- Mark "If you have found a very wise man, then you've found a man that at one time was an idiot and lived long enough to learn from his own stupidity."

Try this link below it got me started: http://www.shorewall.net/ On the introduction page, scroll down to "Getting started with Shorewall" Look for a link to a Quick Start Guide HOWTO.

Hello, I opened port 80 by typing tcp/80 udp/80 in the advanced panel of the firewall setup. Still no access to the net. I removed all the firewall and I can connect again. What did I wrong?

And one more... I red the instruction to setup a firewall. I use my machine since the first MDK installation with no firewall. In my case I had just to remove the "everything" cross and install a package. No problem until I tried to connect to the net or open a website. Nothing works. I go back to the firewall and click in "everything" and I'm back on the net. What shall I do? Is the firewall not just limiting the access to my machine? Thanks for your help.
