Yes, it (almost) always works. I have read that if it does not work, it may be due to the remote station. That is, the one that hosts the game.

I have set up the pfSense according to the instructions and help in the Netgate forum.
The WAN interface of the pfSense is connected to a media converter (RJ45 <-> glass fibre). I don't know if this is relevant.
Yes, I know that. I already deactivated this during the installation.
Yes, I know I should do that. But I can only do it piecemeal because I have to work a lot.
Unfortunately, my English is not (yet) good enough for real-time communication. I always need a translator to help me :-(
I will find out the answers to the questions when I am in the office (home office at the moment).
