Firewall setup

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View


I've a new Linux box (running Debian Lenny) which is connected via a WLAN
card to a DSL router. The firewall of the DSL router is disabled. Now I
would like to install a firewall on my Linux system. Which connections
do I need to block in general? Are there any graphical tools that help me
to setup firewall rules? Or any out-of-the-box scripts that can be used
after a slight modification?

Thank you.

you encounter problems with your connections.

For the other questions: try
