Linux-Firewall.org

Description
This software will give you the opportunity to decide which programs are allowed to connect to a network/the internet and will not just block IP adresses like many others do. Studies have shown that linux is becoming more and more interesting for criminals because the number of users grows every day. So Linux-Firewall.org is the best choice to protect yourself against trojans, viruses, rootkits and non-open-source software trying to connect to the internet without your permission.

It's closed source.

The application is closed source and for it to work, you have to have it installed as root.

installing closed source third party application on your Linux system is a serious security risk.

Don't bother with it because you'll be installing a closed source application as root with no way of verifying the security of it.

Simply don't do it. It's not worth the risk.

Don't use it!

This software is useless. It has major flaws!

* This software doesn't build checksums of programs you allow access to the internet. So replace a previous authorized binary and you can do everything you like
* If you want a software which is written in a intrepreter language like python to have access to the internet, you've got to allow all python-programms
* This software runs with user rights. You can kill it, and have access to the internet.

All in all, peace of crap...

Real Crapware

The author has no idea about networking concepts. He doesn't even know what TCP handshake or stateful packet inspection is. There's been a disturbing discussion with the author (wilson82) in the German Ubuntu community forum. He was pointed to many technical flaws and design errors in his software, (including potential backdoors,) but refused to take any lessons. Although he voluntarily conceded not to be a security expert at all.

Spyware?

could not find any developer's forum for this, so I was suspicious.

Just give it a try.

I have no clue how to use IP tables. Therefore, I could only try a limited number of firewalls. The top three easy-to-use firewalls I like are; Linux-Firewall, Guarddog, and Firestarter. I like Linux-Firewall (L-F) best. Linux-Firewall allows you to control which program(s) can access the web. Other firewalls don't do this. Instead, you end up opening or closing specific ports - which any program can use afterwards once opened. With L-F, you can open a port for a particular program and also restrict other programs from using it. The best feature L-F have is this; it will show you a pop-up window every time a new program tries to access the web, asking whether to allow or block it. This feature is vital to me. I threw a few firewall tests at each firewall and L-F worked to my liking. L-F can even block WINE applications by blocking it's "wineserver" client. Other firewalls failed to block WINE applications. L-F is not perfect, but it fulfilled my needs and has great potential (if they would continue to improve it, or make it open-source). At least try it, you might learn something useful.

try ideco instead

There is one UTM that i can recommend to those who are not linux experts and want to cntrol in-and-out traffic efficiently - ideco gateway
You can set all kinds of restrictions rules per user, per group and more , a firewall web/mail server etc , however it requires a dedicated server so yeah this is what i chose for my network , price is competative comaredto alternatives with such functionality

Exactly the kind of firewall needed for Linux Desktop users

I have been looking for a firewall filtered by applications, IP addresses, and service ports, for Linux Desktop. I have not tried this one yet (due to its close source), but this is exactly the kind of firewall Linux Destop users would need to fully protect their Linux PCs. Majority of the Linux firewalls filtered by only IP addresses and service ports are suitable for servers, but do not provide enough protections for Linux Desktop users.

There was an open-source firewall similar to this one, "fireflier", unfortunately it is no longer maintained. I hope someone would continue that effort.

No matter what other people says, I think the developers of Linux-Firewall.org got the right approach, and I wish them well.
