RAX36S port forwarding

[faja1130]

Hello all,

I am trying to set up a simple HTTP port 80 port forwarding rule to an internal server.

No matter what I do, it will always return a 503 Service Temporarily Unavailable error.

I tried configuring the server to use another port (8080), but still the same.

I am able to access the server fine internally, but once outside coming thru the router/firewall, it fails.

I can see that the internal server is getting the request, it just seems not to let the HTTP page to go out.

The server is running on an Arduino/Adafruit Metro M4 airlift lite and just returning temperature and humidity data.

Thank You

also want to add that when I am connected to the internal wifi network, I can access the external server page using the external ip of the router. (so it seems that something is being forwarded, but only internally?)
