Port Forwarding not working

I created a new port forward for port 8089, but portchecker.io says the port is not open.   I have forwarded other ports for things like Plex, and FTP before successfully, so I can't understand the issue with this one.   I haven't changed another else in my network.

  Hi there, here are some simple checks you can try:

  • Check if there is another rule blocking the traffic. Learn more about rule logic
  • Check if there is double NAT. If you have another router in front of Firewalla with DHCP turned on you may have double NAT. How to see if you have a public IP address?
  • Check if there is a firewall running on your local device, such as a NAS.

  (For more info on port forwarding, please see https://help.firewalla.com/hc/en-us/articles/1500009502622-Create-Port-Forwarding-on-Gold-Purple-Series)

  Let me know if any of the above help with your troubleshooting. If not, I can open a ticket for you, and our engineers can take a closer look.

  I saw this in the app and checked.  I do not see another rule blocking it, no double nat or other firewall.  When I do a scan in the app it shows NO PORTS open.....
