@K3rn3l_Ku5h, thanks for your answer. This would then answer my previous question if something has changed between 4.0.3 and 4.1.0. I will have a look into these articles, and try to get this running, once the release candidate for 4.1.0 is out.
why can’t i add port range to port (only one by one port) forwards?
I don’t think it can be done in the GL.iNet UI but can be done in LuCI or SSH. You are not going to be using the port forwording but changing options in the firewall list to allow a port range.
OpenWRT 22.03.x is migrating from FW3 to FW4 so rules don’t always carryover correctly.
