Quintin, I owe you one!

At long last, via one tiny little setting, I have access to my printer 
via both computers. PC2 is now 10.0.0.4 and PC2 has become 10.0.0.5.

Now I have one more, hopefully last question: how do I set up the PC's 
to network, i.e. so I can "see" one from the other? Do I configure the 
"loopback interface" settings on PC2 into the LAN interface on the router?
