+## DNS Settings
+
+### Loop the proxy into the connection
+To include the proxy in the connection between the inverter and the TSUN Cloud, you must adapt the DNS record of *logger.talent-monitoring.com* within the network that your inverter uses. You need a mapping from logger.talent-monitoring.com to the IP address of the host running the Docker engine.
+
+The new GEN3 PLUS inverters use a different URL. Here, *iot.talent-monitoring.com* must be redirected.
+
+This can be done, for example, by adding a local DNS record to the Pi-hole if you are using it.
+
+### DNS Rebind Protection
+If you are using a router as local DNS server, the router may have DNS rebind protection that needs to be adjusted. For security reasons, DNS rebind protection blocks DNS queries that refer to an IP address on the local network.
+
+If you are using a FRITZ!Box, you can do this in the Network Settings tab under Home Network / Network. Add logger.talent-monitoring.com as a hostname exception in DNS rebind protection.
+
+### DNS server of proxy
+The proxy itself must use a different DNS server to connect to the TSUN Cloud. If you use the DNS server with the adapted record, you will end up in an endless loop as soon as the proxy tries to send data to the TSUN Cloud.
+
+As described above, set a DNS sever in the Docker command or Docker compose file.
+
+### Over The Air (OTA) firmware update
+Even if the proxy is connected between the inverter and the TSUN Cloud, an OTA update is supported. To do this, the inverter must be able to reach the website http://www.talent-monitoring.com:9002/ in order to download images from there.
+
+It must be ensured that this address is not mapped to the proxy!
+
+## Compatibility
+In the following table you will find an overview of which inverter model has been tested for compatibility with which firmware version.
+A combination with a red question mark should work, but I have not checked it in detail.

+```
+Legend
+➖: Firmware not available for this devices
+✔️: proxy support testet
+❓: proxy support possible but not testet
+🚧: Proxy support in preparation
+```
+❗The new inverters of the GEN3 Plus generation (e.g. MS-2000) use a completely different protocol for data transmission to the TSUN server. These inverters are supported from proxy version 0.6. The serial numbers of these inverters start with `Y17E` instead of `R17E`
+
+If you have one of these combinations with a red question mark, it would be very nice if you could send me a proxy trace so that I can carry out the detailed checks and adjust the device and system tests.
