Peer Discovery

The peer discovery feature can be used to find other peers. A set of peers is identified by a common community passphrase.

Peers belonging to the same community will be added as WireGuard peers to the interface configuration.

No other tasks are performed. Paired with other features like the endpoint discovery, auto configuration or route synchronization, the peer discovery is a cornerstone of a zero-configuration peer-to-peer VPN.

In addition to community passphrase, peers can be accepted by white- and blacklist filtering.

The following settings can be used in the main section of the configuration file or with-in the interfaces section to customize settings of an individual interface.
