Unable to acess my services using public ip address

I am running Ubuntu 20.04.3 LTS 64-bit

My local network IP has been DMZ and the port i'm looking to use is forwarded.

when I start my NodeJS process, it is listening on ip 0.0.0.0 on the selected port.

By runnning sudo netstat -tulpn I get the confirmation.

> tcp     0    0 0.0.0.0:9998       0.0.0.0:*        LISTEN    11480/node

Now when I run ifconfig I get this output

docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

If I reach any of these addresses from my PC I get a response back.

But if I try to reach my public IP, I get no response.

I'm not sure what could be missing. The router is forwarding the port to 192.168.2.11

I am listening on 0.0.0.0 which should be all networks. I also have the rule in the firewall, if I run sudo ufw status

I get;

Status: active

9998 (v6)                  ALLOW       Anywhere (v6) 

Would docker have anything to do with it? I'm not starting the app in a container yet since. I start the node process as the user logged in from the terminal plain and simple.

The sudo lshw -C network returns

I will add any input required to get this to work. Just ask for it. Thank you for your time!
