Observations from running a small personal network across Hong Kong and the cloud.
9 November 2026 · OperationsKeeping an IPv6 route understandable
A network is easier to maintain when each machine has a clear role. The entry server accepts connections, the relay selects a destination, and the home machine runs the application.
We keep a record of those roles and check the whole path after a change. A listening port is a useful first check; a completed application request is the stronger check.
Field checklistBefore changing a relay
Save the current configuration, record the addresses and ports, and prepare a way to restore the previous route. Test both address families independently.
