Trouble shooting of remote debugging in PHPStorm

Hello,

I am trying the trial version of PHPStorm for a project here, and I have to use the remote debugging function.

Unfortunately, it does not work at all.

I do see that there is communication between the web server and my machine on port 9000 (tcpdump), and the connection is alive, but phpstorm ... does absolutely nothing. Can I somehow figure out what's wrong here? I have followed each and every single tutorial, and even mixed them together for the fun of it.


Thanks for any help!
/Axel.
