How to allow sending http requests to a computer on the local network?

Question

network hardware

Hello, I am learning to write web applications. For this house, I set up the MTS router so that it was possible to send requests to the computer directly from the Internet (that is, not only via the local network), but the connection via the local network, as if it had already been configured in the router.

Now I live in a hostel and we have another router here - keenetic. With it, for some reason, it will not work to set up even connections over the local network. I have been sitting for an hour now and honestly I don’t know what to “twist” here so that I can send a request to the Apache server running on one computer from another computer on the same network. If anyone has experience with this router and he set up a LAN connection, can you at least give a tip on how to set it up?

The screenshot below shows the control panel, with information about the version of the system on the router. If you need other screenshots, then write, I will try to send quickly.

First, make sure that different devices in your dorm can see each other at all - nothing will work without this.
The cardinal solution that will end all your suffering is to rent a simple virtual machine for a couple of euros a month, which will have a white address and the ability to completely steer the network settings as you please.
