Two Must‑Do Keys to Make RustDesk + ZeroTier Work Reliably from Outside Your Home LAN

1) ZeroTier Managed Routes (both are required)

• <ZT_CIDR>：(LAN): the ZeroTier overlay subnet (ensures traffic to ZeroTier members goes through the tunnel)
• <LAN_CIDR> via <ZT_SERVER_IP>：via : route all traffic to the home LAN via the server node (so the phone can reach the home LAN hbbr/target PCs)

How to set:

• ZeroTier Central → your Network → Routes → Add
• Ensure the phone’s ZeroTier client is Authorized and Online

2) Quick fix for common issue
“ID does not exist”
Check:

• ID Server:
• Relay Server:
• Public Key: the full content of the server’s id_ed25519.pub

Client service not started:

• Open the RustDesk Client GUI, click “Start service” at the bottom, wait until the status shows “Ready,” then try again
