other. Heres the scenario..

>ethernet - 206.136.25.0/24
IP for his dialup: *.60
Netmask: 255.255.255.252
Server's ethernet IP: 206.136.25.61
Workstation 1: 206.136.25.62
Workstation 2: 206.136.25.63
Workstation 3: 206.136.25.64

>I set the internal ethernet netmask to 255.255.255.252, along =
with the
radius setup. I've currently got him doing PAP onto the PM2, but =
I am not
sure if this is correct (I know of the problems with PAP and MTUs, =
wasn't
sure if it was the same with netmasks). =20

>So, I know its possable, but anyone see any problems with this? =
So far I
have been able to get one of his machines to log in (the server) =
using the
252 netmask and all. I'm going to go back in a few days and kick =
it out
completly and see how it acts.

In a nutshell, no. However, the idea will work, I have a very =
simialr setup at home right now.

First, in order for NT to route you need 2 things. You'll need the =
Steelhead Beta software to do dial on demand. You'll also need to =
give him a dial-in IP on a different subnet. NT can only route =
between different subnets.

Here is how I have mine set up at home. I have an NT 4.0 Server =
(build 1381, service pack 2, Steelhead Beta) with my modem hooked =
up and an ethernet card. My ISP gives me a dial in IP of =
xxx.yyy.zzz.140 and routes my subnet through that (block of 8 =
IP's, /29 CIDR notation). I then assigned all of the IP's to my =
devices and built my DNS entries in my NT machine. I also run WINS =
on my server. Then I set up all of the machines with the default =
gateway of my NT server's ethernet address. Then I added a static =
route of 0.0.0.0 subnet 0.0.0.0 to the ethernet adapter and =
pointed it to the IP of my dial in.=20

In your case, your doctor could also set up DHCP on the NT server =
and assign the IP, subnet mask and default gateway to the Win95 =
machines automatically.

Any ?'s, please reply via e-mail and we can take this off the =
list.
