Here you can start and stop the firewall for your LAN.<br>To stop the firewall, a Super Admin password is required.
<br><br>
You can shape incoming and outgoing network traffic.
Simple Traffic Shaping allows you to set a limit on the total bandwidth allowed in or out of the <?php p_mode(); ?>.
<br><br>
To complete the VPN service running on this <?php p_mode(); ?> you have to go to the "Inbound Access" page.<br><br>
If you have a VPN service running on a server inside your LAN, go to the "Virtual Server" page to allow a VPN service for that server.<br>
