I’m trying to set port forwarding rules for port 25565 udp and tcp. I’m new to this on a Mikrotik router, so I’m not sure what to set the various fields of the NAT rule to. Can anyone offer assistance? Attached is a screengrab of what I’m looking at so far, but https://www.yougetsignal.com/tools/open-ports/ is showing a closed port. (Have temporarily replaced my actual IP with a filler)

The only thing you should change from the screenshot config is to remove in-interface=bridge . If you have a static public IP, you could use it in dst-address instead of in-interface-list=WAN. If the rule still doesn’t work, maybe you’re behimd carrier-grade NAT and you should ISP to create a full port forwarding in their router
