	Well, I've just exceeded the maximum cable length of my thinwire
	ethernet.  I picked up PCroute2.0 and PCbridge hoping that I would
	be able to simply extend my ethernet.  PCbridge worked a treat, but
	then I started thinking; ``what about future problems like this'',
	and I took a look at PCroute.  It looked like a simple, inexpensive
	answer that would fulfill my needs for some time to come.  It offered
	slip support which I will need real soon.

	Please bear with me as I am new to subnetting.

	I have only a class C IP address of 192.34.233.x, so I decided to
	grab 3 bits of the host address portion for subnetting.  This will
	allow 7 subnets of 29 hosts each.

	I've set up a test network that consists of the following:

	    Net A (192.34.233.[33..62]) encompasses the following hosts:
		ADDR	NODE	COMMENT
		...33	oetl1	HP series 300 (HP-UX 6.2)
		...34	oetl	HP series 200 (HP-UX 5.15)
		...38	snowyA	AT clone w/ PCroute (1st WD interface at 280h)
		...39	grumpy	AT clone running PC-NFS

	    NET G (192.34.233.[225..254]) encompasses the following hosts:
		ADDR	NODE	COMMENT
		...225	snowyG	AT clone w/ PCroute (2nd WD interface at 2a0h)
		...226	sneezy	VAX 11/750 (VMS 5.1) running CMU TCP/IP
	

	Question 1: How do I (or can I) configure PCroute to pass
		    packets to the different subnets transparently?
		    I would like this to look like a single network.
		    I'm not running routed on any of my machines.

	Question 2: Do I have to tell all of the hosts that they are
		    subnetting, or will PCroute deal with all of that?

	Question 3: Presuming that there is an answer to Question 1,
		    What should I expect when I `ping' snowyA from oetl1?
		    What should I expect when I `ping' snowyG from oetl1?

	Email or post as you see fit.  Thanks.
