Are there any open source firewalls for linux that
- can be installed on a server and bring their own linux OS?
- have a graphical user interface?
Would be great if the firewall
- would be based on Debian linux
- is still supported by an active community
The ones I found are all commercial and not suitable for usage in small enterprises.
PS: I know I could just fiddle with IPTables, but I wondered if there is a product that does not make me to do that.

I would go also with pfsense. It's based on FreeBSD but that should not matter since you probably won't interact much with the operating system itself unless you want to. It uses a nice webinterface for configuration.
If you need linux for some reason there are one project called ipcop (www.ipcop.org) and another called smoothwall (www.smoothwall.org). I prefer pfsense though, because of more features and i'm more comfortable with pf firewall than iptables.
