UPnP
UPnP is short for Universal Plug and Play, which is a networking architecture that provides
compatibility among networking equipment, software, and peripherals. This router has optional
UPnP capability, and can work with other UPnP devices and software.
Enable UPnP
If you need to use the UPnP functionality, you can enable it here.
WAN Ping
Pinging public WAN IP addresses is a common method used by hackers to test whether your
WAN IP address is valid.
Enable WAN Ping Respond
If you leave this option unchecked, you are causing the router to ignore ping commands
for the public WAN IP address of the router.
WAN Port Speed
Normally, this is set to "auto". If you have trouble connecting to the WAN, try the other settings.
Multicast Streams
The router uses the IGMP protocol to support efficient multicasting -- transmission of identical
content, such as multimedia, from a source to a number of recipients.
Enable Multicast Streams
This option must be enabled if any applications on the LAN participate in a multicast
group. If you have a multimedia LAN application that is not receiving content as expected,
try enabling this option.
