I see from viewing other threads that some are finding solutions through other means, like making Fedora revert to using the eth-n names. At least then I would be certain that the iptables firewall is happy. Another suggestion was referring to source by MAC address of the interfaces.
I will try that, or both, but for now I've re-installed F14 on my machines. When support for 14 stops I'll have to see if any of the lost functionality due to the adoption of the new Gnome has been regained and if it's worth staying with Fedora.
Thanks to all that have read my thread.
