Minecraft Server Ubuntu 16.10 - Cant Connect

I have set up Minecraft servers on Windows in the past and was able to connect to them externally no problem. However, after setting it up on Ubuntu it is absolutely refusing to allow external connections.

sudo ufw status
25565                      ALLOW       Anywhere                                   
25565 (v6)                 ALLOW       Anywhere (v6)


netstat -ntlp | grep 25565 
tcp6       0      0 0.0.0.0:25565           :::*                    LISTEN      3228/java 


$ sudo iptables -L --line-numbers | grep 25565
1    ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:25565
2    ACCEPT     udp  --  anywhere             anywhere             udp dpt:25565

I have port forwarded my router on tcp 25565 to my ip address, and yet I am still unable to see myself on canyouseeme.org for 25565 using public ip address.

Minecraft server.properties:

Anyone have any ideas on what I could be doing wrong here?

Hello anyone searching this question, the answer I found is this:

As I was running a wireless router connected to a non-wifi router, I first needed to route incoming 25565 traffic from the non-wifi router to the ip of the WiFi router that the minecraft server was connected to. Then on my WiFi router I routed the 25565 packets to the ip of the connected minecraft server.
