QUESTION
On a Windows machine there are different network interfaces available. One of these interfaces is the TAP interface connected to a VPN-server, with a specific IP (e.g. 10.25.1.9). To reach the host 10.2.1.1 the route leads through this interface.
I want to start a local python server program and bind it to this interface, so I need to know the IP address to bind to. Since this local server program shall be installed on several machines from which I don't know the IP addresses, I want to find this IP automagically.
It can be that there are several VPN connections installed on the machine, so neither a IP address prefix is unambiguous nor the interface name can safely assumed to be unique.
The only safe thing I know about the interface is the fact that through it the host 10.2.1.1 can be reached (probably I will test some simple service on that host to be sure that this is the right one).
I had a look at netifaces but it does not offer this. I also had a look at PyRoute2 but this is not available on Windows machines.
So, my question remains: how can I find out which interface the route to my VPN base host 10.2.1.1 leads through, so I can take this IP to bind to?

Install pyroute2
You can use pyroute2 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
