Docker+php-fpm+Xdebug (on Linux) + PhpStorm (on Windows)

I have Docker installed on my Linux host and raised a container with php-fpm and Xdebug. PhpStorm is installed on Windows server. The project is hoisted through gitlab. Can you please tell me how to set up debugging via Xdebug in such a bundle?

Xdebug ver. 2.9.8

I need to do a setup without DBGp Proxy. It needs to be configured using path mappings. Is this possible?

Linux and Windows servers are on the same subnet, but I still get timeout in Xdebug logs when I open the page.

UPD. Xdebug log

I also decided to use DBGP Proxy, but there are also some problems with it. Tried proxy for both Windows and Linux.

But it didn't work through browser and Postman. And only the request in the terminal via curl hangs, and the proxy on Linux issued the following

Solution

Thanks to all. The problem turned out to be in the firewall. I opened port 9000 and it worked
