firewall, wich one..?

[morteza87]

Greeting all

I wonder if you share your exp on firewalls, which one do you prefer and why..? I'm still not install any firewall, is it necessary for laptops..? if how can I install one?

A firewall is installed by default with Fedora. The system uses iptables, which is the current standard for Linux systems.

I would use the default firewall in Fedora as well. Iptables has been around for a long time and is very stable. Use System / Administration / Firewall to set it up, or "system-config-firewall" from the command prompt. I would highly recommend enabling the firewall on any machine that is exposed to the Internet that is not protected by a physical firewall.

There is only one firewall... iptables.
The only variation you have on that is that there are 1000 different configuration utilities available for it.

Pick which ever config utility you are comfortable with (system-config-firewall is the standard on Fedora), ***IF ANY*** (some people like to deal with it manually).

[szilagyic]

My suggestion would be to use the default app, system-config-firewall (System / Administration / Firewall), and if you need to use more advanced options, there is a section in that utility for Custom Rules. The Custom Rules allows you to link to a file where you can add additional iptables rules. But, unless you are doing advanced routing with multiple NICs, you probably don't need custom rules.

There are lots of types of firewalls (e.g. hardware vs. software, screening vs. host), but I'm guessing you're looking for a host-based firewall since you mention your laptop.

If so, iptables.

Not only is it an able firewall in and of itself, but it is flexible and nearly ubiquitous on modern Linux distros. Knowing iptables will serve you well into the future.

Actually, I'm sure you're probably familiar with host-based firewalls. I bet you've used them before. The term is probably what's unfamiliar. When most people say "firewall" they are talking about host-based firewalls. A host-based firewall is also known as a personal firewall. It's a firewall you run on an end-user computer.

Examples of host firewalls or personal firewalls include ZoneAlarm and Windows Firewall. iptables is also often used as a host-based firewall.

The term is used to distinguish from firewalls you run on the border of a network to screen an entire subnet. Examples of screening firewalls (border firewalls): Astaro, pfSense, monowall, smoothwall, etc. But it doesn't sound like that's the kind of firewall you're looking for.

It looks like you're looking for a host firewall. Just stick to iptables for now. Honestly, just use the built-in firewall configuration tool in Fedora for now and see if that does what you need.

su -
yum install system-config-firewall

System -> Administration -> Firewall
