Port Forwarding

Port Forwarding integration enables to set up rules to allow traffic to pass from the interface Eth0 to devices connected to the interface Eth1.

When 3^rd party devices are connected to Eth1 they are isolated and cannot communicate with other devices connected to other networks.

This kind of setups is often used when devices need to be separated from a corporate network (Eth0) but need to send data to the TNA via MQTT for example.

If these devices need to be accessed via Eth0, for administration purposes for example, you need to create a port forwarding rule using the TNA Web Server.
