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](./epdisc.md), [auto configuration](./autocfg.md) or [route synchronization](./rtsync.md), 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. ## Configuration The following settings can be used in the main section of the [configuration file](../config/) or with-in the `interfaces` section to customize settings of an individual interface. import ApiSchema from '@theme/ApiSchema';
