Use the DMZ entry in the router to point to your server. Total workaround while you get TP-Link to fix it.
Hi! So, as the title reads, this router just won't port forward. I tried using GameRanger to play older games online, but even after creating a forwarded port 16000, it will give me the same message as before, "Port Restricted Cone NAT Router".
Last week, I tried making a Minecraft world public by forwarding the port it created the LAN server. That didn't work: my friend never managed to connect to it, but could connect to other servers (yes, I did give him the IP adress, alongside with the port, format: xxx.xxx.xxx.xxx:PORT).
I also want to mention that I can't seem to create detectable LAN worlds in the network. The world is being opened, but cannot connect to it: it refuses the connection. Why is all of this happening?
