Firewall for Debian 7?
 

Hi everyone, I am coming from using CentOS 6.4 and I feel in love with the firewall (iptables?) that it had. I switched over to Debian yesterday and I have everything working (besides DNS server) on the system and I'm posting here so I won't screw anything up. Id like to install that firewall that CentOS has along with whatever GUI it has if its seperate on my Debian 7 server. If anyone could just link me to somewhere that they know it works and won't break anything that would be great.

My first suggestion would be to open up Synaptic Package Manager and search for iptables. Look through the list of packages and find one that states it to be a GUI for iptables. Personally, I prefer to configure iptables from the command line. Also, search Debian's website for information on iptables. Some of it may be for older distros, but the basics are still the same. The same could be said about searching Ubuntu's support forums for information.

The iptables utility is common across Linux distributions (it's just a way to manipulate the Netfilter functionality in the kernel, which actually does the firewalling). Do you happen to remember the name of the GUI front-end that you used with CentOS (there are several)? If so, try to look for it in the Debian repos with:

Once you have foubd the package, you can install it with:
