infinity connection

[bachelor-SGE]

Describe the bug
So there is a Windows on which ubuntu 22.04 runs with the help of wsl, on this very ubuntu a server inside the local network should be raised so that then I could connect to the local network from anywhere in the world

installation

1. "sudo apt install mc nano wget curl"
2. "wget https://git.io/vpn -O openvpn-install.sh && bash openvpn-install.sh"

Immediately and immediately everything does not work, I open the necessary ports on the router and on the PC, again it does not work, it says that the port is busy, I disable the port in all services, it still does not work in the log and there are no errors when connecting, just an eternal connection

Expected behavior connecting to OpenVPN from a client PC and simulating a local network

**Version information **

• OS: [ Ubuntu 22.04]
• OpenVPN version: [2.5.8]

If you need any other information, please write

[cron2]

"Ubuntu inside WSL" is not "OS: Ubuntu", it's "OS: Windows with some extras"... so I expect this to just not work. From the logs, the TCP connection from the client does not reach the OpenVPN server process, so this is really "outside of OpenVPN to solve".

Running the OpenVPN server on the Windows side should work fine.

[Dibyajyoti-08]

Hello bachelor-SGE,
i will suggest, instead of using Ubuntu inside WSl, just use any cloud server, on top of that you can run your Ubuntu OS, and configure the inbound and outbound rule for the port opening, and then you are good to go.
