Built-in Windows 7 & Windows 2008 R2 tunnelling (point to point VPN)

We have a VISA server & VISA authorizer PC which is linked by a cross LAN cable between them
& we now have a need to shift them apart : server in DC & PC at user's secure room but we'll
need a point-to-point VPN set up to do this for compliance.

We are not allowed to install any 3rd party software on the server & PC.  Does Win 7 & Win 2008 R2
has any sort of point-to-point built-in tool to do this?   We can load ssh (thought of reverse ssh tunnel)
opensource tools too

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Without 3rd party software I do not think that is doable, especially given that Windows 7 lacks a VPN server.

However, depending on your network setup, you should be able to have a VLAN which encompasses only the VISA systems, and have appropriate access rules.

If the two systems are at the same location but in different rooms, you might be able take advantage of the patch panel port to produce the same effect you have had.

It's at different buildings : can a VLAN be trunked across WAN using existing routers ?  Any sample will be good.

Can Win 7 act as client while the Win2008 R2 server as VPN server?  I'm looking at the following:

  Specifically I'm looking at the above: just that I'm unclear whether to use DirectAccess or Teredo or
  encapsulation.  The above link also did not provide step by step (or screen by screen & click by click

With VLAN, it goes thru our core switch : is this protected end-to-end (ie all the way from the PC to the server
or can anyone put a sniffer there to sniff the traffic?) ?

Correction, that VISA server located at our site (owned by VISA) is actually an RHEL, not Win 2008 R2.
I may need to ask VISA tech support ... if they require a tunnel

Yes that is doable.

It's at different buildings : can a VLAN be trunked across WAN using existing routers ?
Yes, but that also assumes that you have a VPN tunnel between the routers of each location.

Who manages the VISA systems? And I would agree that you should check their security requirements.
