Package WireGuard
-----------------

### Configuring WireGuard to work with OpenIPC (VPN implementation)

#### Configuring the server in Linux

Use [this guide](https://ruvds.com/ru/helpcenter/nastroyka-vpn-s-ispolzovaniem-wireguard/) ([archived copy](https://web.archive.org/web/20240804111853/https://ruvds.com/ru/helpcenter/nastroyka-vpn-s-ispolzovaniem-wireguard/)).

#### Configuring the client in OpenIPC

1) In the `/etc/network/interfaces.d/wg0` file, add the `auto wg0` line to the beginning, in `address` specify the desired client address within the VPN network, and in `netmask` specify the VPN network mask. An example of the resulting file:
```shell
auto wg0
iface wg0 inet static
    address 10.10.10.2
    netmask 255.255.255.0
    pre-up modprobe wireguard
    pre-up ip link add dev wg0 type wireguard
    pre-up wg setconf wg0 /etc/wireguard.conf
    post-down ip link del dev wg0
```
2) Edit the `/etc/wireguard.conf` file, taking into account that the `Address` (we set the address in the previous step) and `DNS` keywords are not supported. An example of the resulting file:
```
[Interface].
PrivateKey = MO3+yxTyFnnOgeOk9NKFSKHqgFfW6cBhctUO4YeiwV0=
[Peer]
AllowedIPs = 10.10.10.0/24
Endpoint = 192.168.0.2:51820
PersistentKeepalive = 25
PublicKey = M2/axcXbD+eg/c4vfEQTiIpV6LU+kzgJCGqDpzIpHS4=
```

3) In the `/etc/rc.local` file, add the `ifup wg0` line before the `exit 0` line. An example of the resulting file:

```shell
#!/bin/sh
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

ifup wg0
exit 0
```

4) Reboot OpenIPC.

5) Test: on the server and on the client, run the `wg show` command. Here is its output example if successful:

```
root@openipc-t31:~# wg show
interface: wg0
  public key: /RL2MdZqOdLsT2Be1KXnJWQGJP2oP8sVMlZ/f3GK1BA=
  private key: (hidden)
  listening port: 34161
peer: M2/axcXbD+eg/c4vfEQTiIpV6LU+kzgJCGqDpzIpHS4=
  endpoint: 192.168.0.2:51820
  allowed ips: 10.10.10.0/24
  latest handshake: 1 minute, 7 seconds ago
  transfer: 185.22 KiB received, 182.02 KiB sent
  persistent keepalive: every 25 seconds
