Comodo firewall for Linux?

Does Comodo firewall work on Linux? If not, does anybody know of something that can perform the function of a basic firewall? I don’t know of a single Linux firewall that can block outgoing connections like Comodo can. As if this wasn’t bad enough, people keep saying how unnecessary it is no matter which forum the question is asked on. The user alone has the right to decide what to install on their system, and this often means that a firewall could be a very helpful supplement to their layers of defense.

If Comodo firewall doesn’t work on Linux, is there anything I can do about it? If not, are there any outgoing firewalls for Linux similar to Comodo or that can at least block both incoming and outgoing connections? An incoming only firewall on Linux is as good as useless to me. My router could do the same thing.
