How to open Proxmox KVM ports (Windows 7)?

Question

linux

I run game servers under KVM Windows 7
, I ran into a problem: I check the opening of the port before starting the game, port 7240 is closed.
I start the game server, I check - the port is open. See snapshot prntscr.com/9r529h
The problem occurs when starting the RUST server (port 28015) , it stays closed before and after starting. Windows firewall is off , ports are open in the settings prntscr.com/9r5smt
Using various programs like (PFPortChecker) it is possible to open the port at the time of use, but similar software with only one port prntscr.com/9r5sw6
Help solve the problem, where to dig?

Answer 1

Well, if the server is not running, then why would the port be open if no one is listening to it?
When the game server is running, can you connect to it? If yes, then everything is fine with you, except for the lack of knowledge in networks ...

Answer 2

The server appeared in the lists of game servers, but the problem is that only I can see the server and only I can connect to it, why is that?
