+## ADR-35: WireGuard peers are the devices of the VPN users, kept in the directory
+
+Context: The WireGuard endpoint could be switched on from the Router Manager, but its peers were
+written by hand into `wg0.conf`, so nobody could connect without SSH. A peer is a P2S client like
+an OpenVPN or IKEv2 user, and one person may have several devices.
+
+Decision: A VPN user's entry holds the user's WireGuard peers in the multi-valued attribute
+`vpnRouterWireGuardPeer`, one value `<public key> <IP>[,<IP>...]` per device; the router never
+sees a private key. `PUT /users/<name>` replaces a user's peers after checking the keys, which
+are unique, and the IPs, which do not overlap another peer's or cover the router's address. Setup
+reads the peers of the users who are not disabled from the directory and writes them as a marked
+block of `[Peer]` sections into `wg0.conf`; sections outside the block, added by hand, stay. A
+change of the peers, and disabling, enabling or removing a user with peers, restart setup. The
+Router Manager adds and removes peers on the WireGuard tab of Remote access management, where the
+endpoint is, choosing the user for each.
+
+Consequences: Peers follow their users: disabling a user drops the user's devices, and the
+directory's backup holds them. A peer cannot exist without a VPN user. A change restarts
+`wg-quick@wg0` through setup, which briefly interrupts the other peers.

+WireGuard peers are P2S users' devices: a VPN user of the router's directory may have up to 16
+peers, each with its public key and its IPs, IPv4 addresses or networks, kept in the user's
+entry (`vpnRouterWireGuardPeer`) and set with `PUT /users/<name>` (`wireguard_peers`) or on the
+WireGuard tab of the Router Manager's Remote access management. A key is used by one peer only,
+the IPs of two peers may not overlap, and no peer's IPs cover the router's own address of
+`wireguard.address`. The package owns the `[Interface]` section of `/etc/wireguard/wg0.conf` and,
+between the lines `# BEGIN` and `# END WireGuard peers of the users of the router's directory`, a
+`[Peer]` section for each peer of a user who is not disabled; setup rewrites them when the
+settings or the peers change, and a change of a user's peers, disabling, enabling or removing a
+user with peers restarts setup. Every other `[Peer]` section, added by hand, is carried across
+untouched. While the directory cannot be reached, the users' peers in the file stay as they are.

+    overlap another peer's or cover the router's WireGuard address.

+    hand; changing a user's peers, disabling, enabling or removing a user
