FWBuilder is a nice front end to more intricate firewall setups, as it allows for a single configuration file to be quickly turned into iptables, PF and other firewall configs. One of the disadvantages I saw was that it turned on the forwarding modules of a Linux system even if the firewall was just a local one and not supposed to ever forward anything. It turns out that this can be turned off:

With the modules thus left unloaded, their automatic loading in Linux will still provide a functional firewall.
