Configuration

After installing PiVPN, you’ll need to configure it to suit your needs. Here are the key steps:

Generate Client Profiles: Create a new client profile for each device you want to connect to the VPN.
```
pivpn add
```
Transfer the Client Profiles: Transfer the generated .ovpn or .conf files to your devices. You can use secure methods like SCP, email, or a USB drive.
Edit Configuration Files: You may need to tweak the server configuration files for advanced settings. For OpenVPN:
```
sudo nano /etc/openvpn/server.conf
```
For WireGuard:
```
sudo nano /etc/wireguard/wg0.conf
```
Restart the VPN Service: Apply the changes by restarting the VPN service.

sudo systemctl restart openvpn
```
Or for WireGuard:
```
sudo systemctl restart wg-quick@wg0
```
