<h5>Default Ports</h5>
<p>The default <code>docker-compose.yml</code> file specifies the <b>TCP</b> port range <b>8080-8089</b>. If you wish to change the port forwarding to a different range, you must manually edit the <code>docker-compose.yml</code> file and rerun the Docker Compose step outlined in the <a href="https://github.com/eduardogsilva/wireguard_webadmin?tab=readme-ov-file#deployment">deployment instructions</a>.</p>
<h5>Destination Type: Peer</h5>
<p>Port redirection will prioritize the first Peer IP address assigned a priority of Zero.</p>
<h5>Destination Type: IP Address</h5>
<p>Port forwarding rules will redirect to the specified IP address. Remember to allocate the IP address or network to a Peer.</p>
<h5>Adding a Forward Rule</h5>
<p>Automatically generates a forwarding rule to accommodate stricter firewall settings.</p>
<h5>Masquerade Source</h5>
<p>This serves as a temporary solution when a peer does not use the VPN as its default gateway. It's important to note that this configuration is not recommended, as it alters the source address of all connections to match the IP address of the WireGuard instance.</p>
