ZeroTier

ZeroTier is a private VPN. Joining a ZeroTier network is how you give a remote engineer (or yourself, off-site) direct, private network access to the gateway — it underlies both ForwPort and remote access to the Cockpit console itself when you're away from the plant network.

Network — ZeroTier tab

At the top:

  • Node ID — this gateway's ZeroTier node identifier.
  • Online — whether the ZeroTier client currently has connectivity.
  • Version — the installed ZeroTier client version.

Below that, a table lists every network this gateway has joined, with its name, status, and assigned addresses.

Handle IDs and links as sensitive

A ZeroTier Network ID grants access to whoever has it (after the network owner authorizes the device). Treat network IDs — and any addresses assigned on them — the same way you'd treat a shared password: don't post them anywhere public.

Joining a network

  1. Get the 16-character hex Network ID from whoever manages the ZeroTier network you're joining (often the remote engineer or your integrator).
  2. Enter it under Network ID (16 hex chars).
  3. Click Join.

The new network appears in the table once the gateway has joined it. Note that joining is often not enough by itself — the network's owner typically also has to authorize this device from their ZeroTier controller before traffic flows.

Leaving a network

This may remove remote access

Click Leave on a network's row, then confirm:

Leave ZeroTier network {networkId}? This may remove remote access through it.

If this is the network a remote engineer (or you, off-site) relies on to reach the gateway, leaving it may cut that access off. Make sure you have another way to reach the gateway before leaving a network you rely on.
