I want to set up a PPTP VPN between two Windows 2000
machines, both running professional version.

Is that possible?

Is there any documentation that I can get get from Tech
Net to assist with this process?
I am going to be using static IP addresses on DSL service
to enable this connection. Will I need to make any
changes at the DSL router, and will I have to enable NAT
as well.

Genuine thanks for any assistance that could be provided.

Yes. It is rather complex,...so follow it carefully or it won't route
properly. It is not the same as a "Remote Access VPN" that has "humans"
dialing into it, so don't confuse the two. It is called "Site-to-Site VPN"
or "Router-to-Router VPN" or "Office-to-Office VPN" depending and what and
where you read about it.

There are separate articles for 2000 and 2003 although they are pretty much
identical. I don't know of anything for NT4.0 RRAS and there are differences
in RRAS between the three, especially with the old NT4.0 RRAS.

Sure. See the link below on how to do it. Keep in mind that a W2K Pro computer can
accept only one connection at a time. You will have to configure your router to port
forward to port 1723 tcp and allow protocol 47 gre which commonly is referred to as
"pptp pass through" on common nat routers. I found on a Linksys router [the original
wired one] that I had to disable SPI to allow pptp pass trough to work. I would also
configure the connectoid on your client vpn to connect to your vpn server side of the
connection by entering the public IP address at the server end and if possible
configure your router to accept port 1723 inbound only from your client IP public
address. Also configure your vpn client connectoid in properties/networking to use
pptp instead of auto as W2K will always try l2tp first if auto is selected. --- Steve

I do it myself also, easy enough to do when we only have so much time in the day. I
enjoy reading your advice on the NG. --- Steve MVP Windows Security

Thank you sir!

Hey,...MVP Windows Security? We may have met at the last MVP Summit. I'm
from MVP ISA/Proxy and in a few of the meetings they put us in the same room
together and only spearated us when we dealt with ISA specific stuff. I was
usually sitting with Tom Shinder or Dieter Rauscher most of the time.
 
Hi Phillip.

I was unable to make it this year due to work obligations which was disheartening to
say the least but am very hopeful on next spring. Maybe will see you then. Sounds
like you had a great time! --- Steve
