Miscellaneous Configuration window
Other functions available in Miscellaneous Configuration menu are a Ping test and IGMP enable/disable.
Ping Test
The Ping test functions on the WAN and LAN interfaces. Type the IP address you want to check in the space provided
and click the Ping button. Read the Ping test result in the space immediately below.
IGMP Proxy
The Miscellaneous Configuration window also allows you to enable IGMP forwarding.
This is disabled by default. This setting will not allow IGMP (Internet Group Management Protocol) packets to be
forwarded to the LAN. IGMP is used to manage multicasting on TCP/IP networks—most users will not need to enable
this. Some ISPs use IGMP to perform remote configuration for client devices, such as the Router. If you are unsure,
please check with your ISP. To enable IGMP service to the LAN interface, select Enabled and click the Apply button.
