Relay

How to set this up

  1. Use the relay only for machines behind a router with no tailnet. Everything else is simpler by another way.
  2. Type an address that reaches the observability server from the internet: a public IP or a domain name whose port is forwarded to it.
  3. Tick "I understand" and switch the relay on.
  4. Press Save, then press Update on the observability server so it uses the setting.
  5. Add machines from Add machine > "It cannot be reached directly". Machines that joined are listed on this page.

Something not working?

  • Saving changes the setting only. The observability server must be updated to apply it.
  • A machine does not join: check that the port is forwarded and the address is reachable from that machine's network.
  • The address changed: use a domain name or a DHCP reservation so kits and joined machines keep working.
  • Revoke a kit you no longer trust from the Add machine step that shows it.
