# Add WireGuard Configuration Peers

To add a peer, click the "+ Peer" button in your configuration.

Once you click the button, a form similar to adding a configuration appears. Fill in the following fields:

* **Name**
  * This is not required. You can leave it empty or provide any name you like.
* **Private Key & Public Key**
  * Required. Both Private and Public Key will be auto-generated.
  * If you want to use your own key pair, toggle the switch "Use your own Private and Public Key".
* **Allowed IPs**
  * The IP addresses assigned to this peer. An address will be auto-generated with the first available IP.
  * You can add more IP addresses by clicking the "Pick Available IP" button, or type custom IP addresses directly into the input.
* **Endpoint Allowed IPs**
  * The IP address range whose traffic you want to forward. For example, to forward only the subnet traffic, set this to match the configuration's Allowed IPs.
  * To forward all traffic through WireGuard, set it to:

    ```
    0.0.0.0/0, ::/0
    ```
* **DNS**
  * The DNS servers this peer will use.
* **Pre-Shared Key**
  * Toggle this for an extra layer of security. WireGuard can use an additional symmetric pre-shared key between the server and peer.
  * More information: [WireGuard: Next Generation Kernel Network Tunnel, 5.2 - Optional Pre-shared Symmetric Key Mode](https://www.wireguard.com/papers/wireguard.pdf)
* **MTU**
  * The MTU is automatically determined from the endpoint addresses or the system default route, which is usually a sensible choice.
* **Persistent Keepalive**
  * If a peer is behind NAT and connects to a public peer, the NAT-ed node must regularly send outgoing pings to keep the connection alive in the NAT router's connection table.
