Problem Routing Network through ISDN on Sparc 10

I'm attempting to connect an ISDN box (a Combinet 2060, if it makes
any difference) to my Sparc 10 in order to do a network-to-network
connection to a remote site. Here are some details:

IP number of local Sparc 10 machine: 130.151.X.Y
IP number of local ISDN box: 130.151.X.Z
IP number of remote ISDN box: 144.15.A.B
IP number of remote machine: 144.15.C.D

The local ISDN box is connected (physically) to le1, so I think I
need to do an "ifconfig" on le1, then a couple of "route" commands,
and then set up an entry in the hosts file, but I'm having trouble
figuring out which numbers go where. If I've got the whole concept
wrong, feel free to tell me that, too.

Oh - running SunOS 4.1.3 - nothing special about it, and I am able
to connect directly to the ISDN modem, via kermit, and dial up the
far end and get connected, but when, after setting things up as I
think they should be, I try to telnet to the remote machine, I get
a "network is unreachable" error.

Is this how to go about asking for clarification of an expert's
answer?


Yes, I think so :)

The machine that the local ISDN box is connected to does have
two separate Ethernet connections - one connected to the local
network, and the other connected directly to the ISDN box. The
way this is supposed to work is that this would isolate the rest
of the network from the traffic coming through the ISDN box, as
well as shielding their network from the brunt of our traffic.

What the intent of the connection is is to, once their machine
is dialed up, make it seem as if our machine is directly on their
network - I'm not clear as to the difference between bridging
and routing, but what we want to be able to do is run, say,
"telnet remote_machine_name" from the local Sparcstation, and
have it connect up automatically. There may be several remote
machines that we'd like to connect to, although I suppose we
could probably do that by logging onto a single remote machine
and going from there to any of their other machines.

I tried the route commands you suggested, and they do get the
ISDN box to autodial, so that part is fixed, so if you could just
explain this routing vs. bridging thing, we could wrap this up.

Thanks for the info so far...

Your local SPARC 10 doesn't know the route to the remote site.
The remote machine doesn't know the route to the local site.
I suggest that you use the 'route add' command on both machines.
