The wired network interface has an IP of 192.168.0.1.

I changed the settings to match what you recommended.  No joy using
Network Manager.   One problem is that the IPV4 settings don't make any
sense.   If I set the Wifi port to "share this with other computers", it
doesn't get an IP address assigned to it.  Hmm... 

There is an IPV4 setting of "Local Link"  I wonder what that means.
NetworkManager doesn't appear to have a help system ?

So, I reverted to using system-config-network and firestarter.  I
disabled NetworkManager controlling the devices.  Firestarter kept
saying that eth0 wasn't ready and crashing.   I know I've run into this
problem before with statically configured ports and firestarter, but I
can't remember what I did to fix it.

This is way harder than it needs to be !

I'm hoping the Network Manager in F12 will be a little more refined.
