Ok, here is what you should do.  Since the NeXT is using Slip to get to the
outside world, it has TWO network interfaces, call them slip0 and en0.  Each
of these should have its own ip address.  The slip0 interface will get its
ip from the slip server you connect to.  The en0 interface will get its ip
address from /etc/hostconfig.  Now, you have two choices

1) set up an internal ethernet network with no access to the outside world.
2) set up an internal ethernet network with access to the outside world.

Choice one is easy, choice two involves setting routed on the next, and getting
you slip prrovider to set you up with a subdomaine, which they might or might
not be willing to do.  I can't help you out to much with this one.

As for choice one, do it this way....

Using /etc/hostconfig, set up as

HOSTNAME=somename
INETADDR=xxx.xxx.xxx.1
ROUTER=same as above
IPNETMASK=255.255.255.0
IPBROADCAST=xxx.xxx.xxx.255
NETMASTER=-YES-


Now, you have a router and netmask to give the mac, ie the same as the above.
Ip address for the other machines in you home ethernet should be of the form
xxx.xxx.xxx.n where 1<n<255

You can also set the next up to run bind and named and then have nameservice 
for your home network, but you probably don't need this.

This should all work.  Since your home network won't have any connection to
the outside world, it doesn't matter what the ip network you chose is.  
If you want to try to get the home network connected to the outside world,
talk to your slip provider, and get copies of the Nutshell books on
routing, and named/bind as you will need them.  Frankly, I doubt it is worth
the trouble.  

Amanda (or others) if I goofed on here please let me know, this is coming off
the top of my head...

Erm, I dunno much about NeXT, but FreeBSD (and other Unixes) can
run quite happily with the SLIP i/f address set to the ethernet card
address, since routing is done by the SLIP's destination address,
not by it's local address (AFAIK). I can say this (with a bit of
uncertainty) as the machine I am sending this from has a SLIP i/f to
Netcom (designation 'sl0'), and a Ethernet i/f toa 10bT LAN (designated
'ed1'). Both have been ifconfiged to have the same local IP address, and a
default route has been set to the gateway machine at the other end of the SLIP
link, with the ifconfig for the ed1 card setting the route
to the LAn correctly. Unless NeXT does things differently, only
one IP address should be needed by the NeXT. Certainly,
2 (or more) IP addresses are needed for machines with multiple IP i/f's
of a more traditional nature (ethernet, FDDI, etc), but I think most SLIP
implimentations would fall over if the 'en0' and the 'sl0' were given
separate IP addresses.

*However* I could be wrong, but this setup works fine for us.

Again, AFAIK, routed isn't needed unless there are multiple possible
routes to the smae destination. All that is needed for SLIP is a default
route entry, made just after the SLIP interface is brought up.

Hope this help, and doesn't confuse anyone!

BTW: Can anyone give more details of the Nutshell routing book,
     e.g. ISBN, etc? Thanks
