Managing VPN Clients

To create and manage VPN clients, use the following commands:

• Create a new client:

pivpn add

• List existing clients:

pivpn list

• Revoke a client’s access:

pivpn revoke

• Generate a client configuration file:

pivpn -c <client_name>

Configuring VPN Server Settings

To modify your VPN server’s settings, edit the configuration file located at /etc/pivpn/pivpn.conf. Some important settings include:

• PROTOCOL: The VPN protocol (OpenVPN or WireGuard)
• PORT: The VPN server’s port number
