This is yet another "cant' set up a Minecraft server" post ... I hope someone is capable of helping. gslist is that the server works on my computer, but not on his. Our computers are connected via Ethernet cable directly to the ASUS RT–AC86U router. The IP address of his local computer is 192.168.50.166. These are the settings for port forwarding: Service Name: Minecraft Source IP: (blank) Port Range: 25565 Local IP: 192.168.50.166 Local Port: TCP: 25565 BOTH If he is running Minecraft on his own computer and directly connects to 192.168.50.166 and connects. However, if he enters the external IP (obtained via the "Network Map" page of the router's settings) this will result in the error: Failed to connect to the server io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information If I try to connect from my computer to 192.168.50.166, I get the exact error from Minecraft. But here's the real kicker ... If I run the server on my computer (192.168.50.48) and change the Local IP port forward settings accordingly, EVERYTHING WORKS. I can connect to the Minecraft server with either my local IP or the external IP.
