Enable NAT

If the LAN is configured with a private IP address, the user should select this

checkbox. The user can then configure NAT-related features. If a private IP

address is not used on the LAN side, this checkbox should not be selected, so as

to free up system resources for improved performance.

Enable Firewall

If the firewall checkbox is selected, the user can configure the device firewall.

Enable IGMP Multicast checkbox

Tick the checkbox to enable IGMP multicast (proxy). IGMP (Internet Group

Membership Protocol) is a protocol used by IP hosts to report their multicast

group memberships to any immediately neighboring multicast device’s.

and reboot. The Web UI will not respond until the device is ready. The

Web UI should refresh to the default page automatically.

subsection 3.3 Login Procedure.
