	Thanks Max, all addreses are 192.168.0.x.  From Wireshark, the rejected
packet is coming from and returning to 192.168.0.6 (laptop).  I don't
know where the 192.168.122. came from. 

	I've re-installed F8 on the laptop to start with a clean slate, but the
same responses are coming from the gateway box.  The laptop has that
same rule pair for 192.168.122.0/24 addresses as its original setup, so
there must be a purpose to it.
