Custom Telebit Server Setup Guide

There are three components to a telebit configuration:

1. the telebit relay
2. the management (authentication) server
3. (optional) DNS-01 and/or HTTP-01 ACME relay

DNS

• devices.example.com and *.devices.example.com should have A (and AAAA) records pointing to the tunnel server
  • https://devices.example.com/ is TUNNEL_RELAY_URL
  • devices.example.com is the primary or base domain for the devices telebit-mgmt --domain devices.example.com

All of the devices need to be under the same domain. You are limited by Let's Encrypt to 10-20 certificates per week. We can solve for this in the future if needed - either by adding more domains or by adding devices.example.com to the PSL (the stated reason would be for browser security, NOT for Let's Encrypt limits).

• Other domains can be pointed to the same server. For example:
  • It would be OKAY to use tunnel.example.com as TUNNEL_RELAY_URL.
  • It would be OKAY to use auth.example.com as AUTH_URL
• It is fine to have the AUTH_URL on a different server.
• having multiple tunnel server URLs is NOT supported, but this is a relatively small change to the telebit-mgmt in the future
