UPnP
By using the Universal Plug and Play (UPnP) protocol, a host on the LAN side can require
the router to realize the conversion of specific port, so that an external host can access
resources on the internal host when necessary.
For example, if MSN Messenger is installed on Windows ME and Windows XP operating
systems, UPnP can be used for audio and video conversations. In this way, functions
restricted by NAT can work properly.
Choose Advanced Network > UPnP on the left pane or click UPnP in the ADVANCED
NETWORK page to display the following page.
In this page, you can enable the UPnP function and select a WAN connection.
After setting the parameters, click Apply to save the settings.
Note
UPnP is widely used in video and audio software. It can automatically search a
device on the network. If you worry about the security problems caused by UPnP,
you may disable UPnP.
IGMP
IGMP snooping is used to manage and control multicast. When a layer-2 Ethernet switch
receives an IGMP message transmitted between a host and the router, IGMP Snooping
analyzes the message to establish and maintain MAC multicast address list, and the
multicast message issued by the router will be forwarded according to the list. This
decreases traffic flooding at the port of receiver that has not registered as a multicast group.
IGMP Proxy enables the device to capture IGMP messages from the host machine via
Ethernet interfaces and send the messages via the WAN interface. When this function is
enabled, this device acts as a proxy agent of the host machine.
