Relay nodes

A relay is a stable KnotRoute node that contributes routing capacity and path diversity.

Listen and advertise

{
  "listen": ["0.0.0.0:7447"],
  "advertise": ["relay.example.net:7447"]
}

Advertise only endpoints other peers can actually reach.

Firewall

A public relay generally needs inbound 7447/tcp. Dashboard and local proxies should remain loopback-only.

NAT

An outbound-only node can still participate as a client, but it should not advertise an unreachable private or loopback address as a public relay.

Upgrades

Use rolling upgrades for backbone nodes and confirm rejoin plus an external .knot request before moving to the next relay.
