Subject:	Internet gateway for remote LAN with both VMS and NT machines

Bill,

NT workstation can be used as a router.  It can make a PPP connection to 
an ISP and route traffic from a local LAN (ie your Alphastation).

1. Serial port address must be on a different network from LAN port address

2. Gateway address in network control panel should be removed (yes, this 
seems wrong)

3. An registry entry needs to be created and another changed.  There is an
article on the MS web site on which. Once you find that article, guard it
or someone will say, "Aha, that is how it is done" and walk away with 
your article.

4. Your ISP needs to set up routing to the network on your LAN.  This may 
be done with static routing and a dedicated dial-in on the ISP side, or 
with Radius (DRAS)  assigning a port address based on your PPP login.  
DECserver 700 has the necessary capability on the ISP side.

Once this is all set up it works quite reliably.  A couple of weeks ago
(American Numismatic Association convention in Cincinnati), I set up a
Alphaserver 2000 running VMS v7.1 and copy of ANA's membership system and
WWW server (a copy of www.money.org and anamarket.money.org) to run
registration and show their web sites.  There was a DS 700 on the
convention LAN with a bunch of VT's (30 minutes training to operators) and
2 NT 4.0 SP3 Multias (one as router to the outside world) for browsing
local and remote sites.  VTs could telnet out for occasional external
inquiries and for making table assignments for the next convention. 

The ANA thought this was a vast improvement to their former strategy of 
using PCs which didn't work very well and never produced a usable 
database of convention visitors.
