[Sunhelp] Problems with Sun3 and Ethernet network

[Wolfgang Engelien]

Hi Tim,
two questions.
1 - is your "home network" directly (that means
	without any routers in between) on the hub?
	If not,
	a)you can setup 3 different networks:
	  One for your office
	  One for your home
	  One for the connecting network
	  Setup the routing and you are done.
	  If you don't have a network at home you
	  can forget about that network.
	b)if for any reason you cannot change
	  given IP addresses you can setup
	  two firewalls and have everything
	  within the 10.0.1 network.

2) your ethernet address seems to be a little
	short. Is this a copy/paste error?

Cheers,
Wolfgang
