And, since you said you had the problem in a F20<--->F20 situation I'd use wireshark on the receiving side as well to check what is being received. 

And, in the event that the F20 systems are connected via 10BaseT to ports on your gw....I'd reboot the gw.  :-)

If you can't laugh at yourself, others will gladly oblige.
