Firewall Applied Knowledge -- Is there a tutor to walk me through?

Ubuntu LXC

I have no clue as to how to setup and configure a firewall. I need to acquire enough applied knowledge to handle my firewalling needs for the servers I plan to have within LXC (I can create LXC containers, now I need to go the next step). I want to end up using Shorewall. I have been through a lot of reading on the firewall subject, but haven't found anything that clicks for they all assume I have a working knowledge and I don't...and consequently, I am forgetting what I have read and worst of all, I haven't created anything! I need something that orientates me as I go, so that I understand why something is being done and can visualize things.

Is there a tutor or something written up that guides me through creating a simple firewall and evolves me into more complex versions? Is there a master listing of firewall commands somewhere, explaining what those commands do? (I have looked for that list, and only find parts and peices.) I need somewhere to start that lets me build and use stuff, so that I am getting a feel for things as I go.

I've stared at this whole thing way way too long. What do you recommend?

If you want to end up using Shorewall then you don't need to know the firewall(iptables) commands, Shorewall simplifies your firewall management. Have you tried the getting started guide?

It's been a long time since I looked at it. I will go and re-read it. Maybe I missed something. For some reason I have been looking at iptables stuff.
