Port forward problems

I was trying to configure port forwarding on my modem and there it is the configuration:

here is the room configuration in Citra:

seems like my friend cannot join the room because port forwarding is not actually working. I also checked with some sites that try to use port forwarding, but the port seemed closed. I set a static ip address and disabled windows firewall, but still, the problem persists.
thanks a lot to everyone who can help me with this.
