I have seen this question, but it doesn't have a good response and what I am looking for is a little different.
I have a well working environment (New York) with a Juniper router that allows me to establish a VPN connection to it. It works fine.
I also have a rogue Windows Server (Chicago) in a different location that need a stable point-to-point VPN connection, as both environments need to connect to each other over a secure connection without any user involvement. That's why a client based solution cannot work.
The optimal solution would be to establish a Juniper router in Chicago, but that's not possible under my circumstances, so I need a way to set it up directly on the server. Both Chicago and New York need to be able to contact each other over the VPN, so it has to be both ways.
How do I approach this?
