I have 4 emonTx + Rpi running emoncms on a local network. Each has a fixed IP address and a different device/host name … emonpi-node-11, 12, etc.
There is a 5th RPi on the network running Raspbian but that could be changed to emoncms.
I want to port forward a request from the 5th RPi to any one of the 4 emonTx/RPi’s running emoncms so that I can log in and see the inputs/feeds/graphs/etc for that particlular emonTx/RPi.
Extensive googling provides much info about port forwarding but it is extremely complex/irrelevant because it focuses on port forwarding via the internet (from outside the local network).
The OEM resource guidance is not helpful as it refers to port forwarding via the internet describing it as complex & insecure.
Any info or pointers to my much simpler objective (within a local network) would be most welcome.
