[SOLVED] Difficulty With Minecraft Server

This is another "cant set up a Minecraft server" post ... Hoping that someone will be able to help. The short version is that the server works on my computer, but not on his.

Both of our computers are hardwired directly to the ASUS RT-AC86U router using an Ethernet cable. MINECRAFT of his local computer in the US is 192.168.50.166.

These are the settings for port forwarding:

Service Name Minecraft Source IP (blank). Port Range: 2565 Local IP: 192.168.50.166 Port: 25565 TCP: BOTH

When he plays Minecraft on his own computer and connects directly to 192.168.50.166 the connection is established. However, if he enters the external IP (obtained via the "Network Map" page of the router settings) it will give the error:

Failed to connect to the server io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information

I''m getting the same error from Minecraft when I try to connect to 192.168.50.166 from my own computer.

Here''s the best part: If I run the server on my computer (192.168.50.48) and change the Local IP port forward settings in accordance with the settings, everything works. I can connect to the Minecraft server using either my local IP or the external IP.
