Using a wifi extender.

Where my spa pump is located it is in a wifi black hole. Move about 10 feet in any direction and the connection is good, but where it sits is a black hole.

Using an ESP32 I had laying around and https://github.com/dchristl/esp32_nat_router_extended I was able to create a wifi repeater network that I could connect the spa device to the repeater network and in turn my home network. Because it is technically on a different network, I have port 8080 forwarded in the repeater to the Lay-Z-SPA device on port 80.

When I have my phone connected to my home network, I can access the webpage on the device at 192.168.1.90:8080 but none of the controls work and the data is unpopulated. If I connect my phone to the repeater network, and connect to the Lay-Z-SPA device by its actual IP, everything works as expected.

Are there other ports I need to forward or something else I need to configure so that I can keep my phone on my home network and have the Lay-Z-SPA device on the repeater network and work correctly? Other posts have mentioned about the dangers of exposing ports to the internet, but this is not a problem because it is still behind my main home network's firewall.

I was able to get it to come up by also forwarding port 81. Since this will be the only device on the extender network, I am not worried about breaking other devices by forwarding those ports.
