Unfortunately that makes two of us. But I'm seeing a definition evolve as incoming replies nibble around the edge of my ignorance.
It's a good idea to have at least a good basic understanding about how a firewall works before you set one up. From there, you could look at tools like shorewall.
I perhaps know just enough to be dangerous. I think I can follow descriptions that tool-makers say about what their tool does. But I might not recognize that it does *NOT* do something I need.
There's also a GUI application the name of which I forgot which allows you to create firewalls. I found it surprisingly good. Fwbuilder?
There is a page (wiki?) which lists URLs of related tools. When I first came across it, I found the lack of adequate descriptions so severe as to make it useless. If it was a wiki page maybe I now know enough to select useful information from the URLs and add it to the wiki.
I still have a very good tutorial that uses iptables and helps you to learn how to build a firewall. I've archived it for reference in 2003. I could send it to you by email if you like (760kB).
YES. Please.
