# Wireguard
 | 
						|
 | 
						|
User-space implementation of the Wireguard protocol.
 | 
						|
 | 
						|
::: danger
 | 
						|
**The Wireguard protocol is not specifically designed for circumvention purposes. If used as the outer layer for circumvention, its characteristics may lead to server blocking.**

## InboundConfigurationObject
 | 
						|
 | 
						|
```json
 | 
						|
{
 | 
						|
  "secretKey": "PRIVATE_KEY",
 | 
						|
  "peers": [
 | 
						|
    {
 | 
						|
      "publicKey": "PUBLIC_KEY",
 | 
						|
      "allowedIPs":[""]
 | 
						|
    }
 | 
						|
  ],
 | 
						|
  "kernelMode": true, // optional, default true if it's supported and permission is sufficient
 | 
						|
  "mtu": 1420, // optional, default 1420
 | 
						|
}
 | 
						|
```
 | 
						|
 | 
						|
> `secretKey`: string
 | 
						|
 | 
						|
Private key. Required.
 | 
						|
 | 
						|
> `mtu`: int
 | 
						|
 | 
						|
Fragmentation size of the underlying Wireguard tun.

<summary>MTU Calculation Method</summary>
 | 
						|
 | 
						|
The structure of a Wireguard packet is as follows:
 | 
						|
 | 
						|
```
 | 
						|
- 20-byte IPv4 header or 40 byte IPv6 header
 | 
						|
- 8-byte UDP header
 | 
						|
- 4-byte type
 | 
						|
- 4-byte key index
 | 
						|
- 8-byte nonce
 | 
						|
- N-byte encrypted data
 | 
						|
- 16-byte authentication tag
 | 
						|
```
 | 
						|
 | 
						|
`N-byte encrypted data` is the MTU value we need. Depending on whether the endpoint is IPv4 or IPv6, the specific values can be 1440 (IPv4) or 1420 (IPv6). If in a special environment, subtract additional bytes accordingly (e.g., subtract 8 more bytes for PPPoE over home broadband).

						|
 | 
						|

 | 
						|
 | 
						|
> `peers`: \[ [Peers](#peers) \]
 | 
						|
 | 
						|
List of peer servers, where each entry is a server configuration.
 | 
						|
 | 
						|
### Peers
 | 
						|
 | 
						|
```json
 | 
						|
{
 | 
						|
  "publicKey": "PUBLIC_KEY",
 | 
						|
  "allowedIPs": ["0.0.0.0/0"] // optional, default ["0.0.0.0/0", "::/0"]
 | 
						|
}
 | 
						|
```
 | 
						|
 | 
						|
> `publicKey`: string
 | 
						|
 | 
						|
Public key, used for verification.
 | 
						|
 | 
						|
> `allowedIPs`: string array
 | 
						|
 | 
						|
Allowed source IPs.
