WireGuard configuration is available in the menu item VPN servers->WireGuard

Select the WireGuard interface you want to change and click on the Edit button

You must understand that changing any interface parameters will completely remove all old configuration and create an interface with new parameters.

In case of changing critical parameters, each client must reconfigure the connection taking into account the new configuration.

You can change the following parameters of the WireGuard interface

• Private key/Public key - Keys for encrypting the traffic of the WireGuard interface, the system generated new keys, but you can set them yourself when creating the WireGuard interface
• IP/MASK -The parameters of the internal network of clients of this WireGuard interface, the address that is specified will be assigned to the interface and for all clients of this interface it will be the default gateway.
• Internal Traffic - Allow or deny traffic exchange between the client of this interface
• Port - Port on which the interface will listen for incoming connections
• External IP - The public IP address that will be used in the interface configuration, NAT will be organized through this address for all clients of this interface. The address must be public and configured on the server.
• DNS 1/DNS 2 - DNS servers that will be issued to the client of this interface
• Bandwidth download/Bandwidth upload - conditional value for the throughput of each peer connected to this WireGuard interface. This data will be automatically applied when creating a VPN client for this WireGuard interface.
• Persistent Keepalive - A sensible interval that works with a wide variety of firewalls is 25 seconds. Setting it to 0 turns the feature off, which is the default, since most users will not need this, and it makes WireGuard slightly more chatty
• MTU - Ability to set MTU on the WireGuard interface. This parameter is involved in generating the client settings configuration.
• AllowedIPs - This parameter is involved in generating the client settings configuration.
• IKEv2 Enabled - Enables IKEv2 protocol support for this interface. If set to YES then users of this interface will connect to the server using the IKEv2 protocol
• IPv6 - Enable or disable IPV6
• IPv6/MASK - IPv6 subnet to be distributed among peers
• DNS 1 IPv6/DNS 2 IPv6 - IPv6 DNS servers
