ZeroTier remote maintenance

ZeroTier remote maintenance of LogicMachine #

Make sure that LM has valid gateway / DNS settings and UDP port 9993 is not blocked on your firewall

Task #

You can access your LogicMachine from the internet in several ways. One is port forwarding on your central router (not recommended due to lack of security). Another way is using VPN connection from your laptop to your central router (very secure, but requires access to the central router). There is also OpenVPN connection possibility between LogicMachine (client) and server (in this case you need to have an OpenVPN server somewhere on the internet; this requires quite complex setup work and involves regular maintenance costs).

The most optimal way is to use ZeroTier which provides the same security level, but makes it very easy to set up.

You can program a KNX/TP line that is connected directly to LM and any other lines via IP Routing (Pass ind. telegrams via IP Routing option must be enabled in KNX connection settings). Unsecure tunneling can be safely used because the ZeroTier connection is already encrypted.
