Advanced Networking

Anchor's networking stack is closely based on Lighthouse's. We refer to Lighthouse's page on Advanced Networking, but want to outline several important differences:

  • Currently, Anchor does not support UPnP.
  • Anchor uses ports 12001 (UDP), 13001 (TCP), and 12002 (UDP) by default.
  • Anchor does not yet support ENR auto-update - we therefore recommend manually setting publicly reachable ports via the --enr*-port CLI parameters to advertise your node as reachable on the network.
