How can I access both my local LAN and a VPN on my terminal server?

Hello Experts, here is the deal:

We have a Windows Server 2008 R2 terminal server with every application we could possibly need... Except one. There is a hospital we deal with that requires us to use a VPN to access their apps. What I need to be able to do is access both our LAN, and the VPN at the same time from our server. The server has 2 NIC cards, I just need the steps to do this. The VPN is a "stock windows VPN", as in one created in Control Panel, not Cisco clients or anything, just a simple PPTP VPN.

Ask away if you need more details. Thanks!

Not very familiar with the Windows VPN, but I would assume that it a configuration on the hospitals end. They probably don't have split tunneling enabled due to security. You may not be able to correct this.

Otherwise look at this article. If you can do it, this looks like how to do it.

I figured that if each of the two NICs were dedicated to a separate network somehow, that split-tunneling wouldn't matter because the NIC that is running the VPN is separate from the NIC for the LAN?

but if it makes the metric lower than the other NIC, it will still go through the VPN.

Could you clarify that if possible please?

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

the metric is what determines what route is used if there are multiple routes defined for the same subnet. If the VPN route has a lower metric, it will be used. However I think that if you follow that link you should be able to change the behavior of the VPN and not use it as the default gateway.

It doesn't seem to want to work even if I uncheck the default gateway option.

sorry, i wish that I could help more, but as I said I am not very familiar with the Windows VPN. You could call the hospital and ask if split tunneling is a possibility.

Agree with earlier poster, the hospital to whom you are connecting controls the VPN parameters e.g. can you split tunnel or not. You will need to get them to agree to allow it. You might also try on the second interface host routes.

Thanks. Split tunneling must be enabled at the hospital's end for any of this to work.
