Anybody know anything about firewalls?

[Hal Murray]

I recently setup a new system (Fedora) to replace a box that had died and 
thought it was working OK.  Then I noticed that another box was having 
troubles connecting.  Eventually, I figured out that the firewall was blocking 
the NTS-KE connection attempts.  (Normally I run without firewalls so I'm not 
conditioned to thinking about them.)

Should the quick NTS setup mention this?

Should we document how to fix this?  How much do firewall configs vary between 
OS-es and distros?
