If more granular rules are required note there is a new interface **wg0** where these may be configured.

The final piece is to allow traffic from the WireGuard network. First define an alias (e.g. **VPN_clients**) and include in it the IP addresses (e.g. 10.10.10.2 and 10.10.10.3) or subnet (e.g. 10.10.10.0/24) of the WireGuard clients from which traffic is to be allowed. Do this via :menuselection:`Firewall --> Aliases` (click **+** in the bottom right).

Then create a firewall rule via :menuselection:`Firewall --> Rules --> WireGuard` (click **+Add** in the top right), with the following information (if an item is not specified, leave it set to the default value):

=========================== ================ =====================================================================
**Interface** WireGuard *The interface this rule applies to*
**Source** WireGuard net *Source subnet*
**Source** VPN_clients *Source subnet - use the alias defined as above*
**Destination** any *Traffic destination*
**Description** WG WAN to LAN *Optional - provide a description*
=========================== ================ =====================================================================

.. Tip::

If you have only one local WireGuard instance and only one WireGuard endpoint configured, you can use the default **WireGuard net** as the source rather than defining and using a new alias.

.. Hint::

Rules defined under :menuselection:`Firewall --> Rules --> WireGuard` take precedence over rules individually configured for each tunnel.
