Reverse-VPN-like connectivity
-
Hi, Scenario: There are two isolated networks A and B with systems and applications (all Windows environment) Network A - Client AC1 - Server AS1 Network B - Server BS1 "AC1" initiates a VPN-like connection and connects to Network B. "AC1" then connects to a web application hosted on "BS1" "BS1" in turn needs to connect to a Web Service hosted in "AS1" using Network A credentials of user on "AC1". Is this possible? What do we need to ask the Network team of A and B to do in order to achieve this? Thanks in advance.

Should be easily do-able via tunneling. VPN on AC1 alone won't get your BS1 server a good route back to AS1. If it's a simple web service that doesn't require a lot of security, you could always give AS1 a real internet addressable address (from your ISP) and BS1 can access AS1 web service over the web. The thing about web services is that they typically aren't blocked by firewalls, but you still need to have an IP address facing the internet for AS1.

Hi Albert, Thanks for the info. Providing internet addressable address is good idea - I will check with the team about it :thumbsup: Web service on AS1 does require authentication, but it must be Windows authentication of Network-A for that user!. In case of any other possibility or possible blockades that we might face, do let me know :)

There is a good discussion on how to configure a reverse VPN tunnelling. Look like connecting back to the system is complicated issue. The essence of your problem is that even you can do the DNS registration (which makes eligible for the servers to find each other), the actual ip connection between your machines is further impossible.
