How can people in a local network connect to my server as clients? (listen server)

I’d like to play a multiplayer session (LAN) with some friends who have the same version of the game.

But how do my friends connect to my server?

Let’s say we all are connected over Hamachi/Tunngle etc. but how do they connect to me (I’m the server)?

You need to provide them with your IP.

If you’re on windows, just open a command prompt and type the following command:

ipconfig

then you will get a bunch of entries where you see some IPV4 address similar to this:

IPv4 Address. . . . . . . . . . . : 169.254.80.80

Test all those addresses with a friend and then, take note of the one that did work.
