Remote Management 
Allows you to enable to disable remote management. This feature 
allows you to access and manage your gateway settings from the 
Internet when you are away from home. To allow remote access, 
select Enable. Otherwise, keep the default setting, as Disable. The 
protocol HTTP is required for remote management. To remotely 
access the device, enter https://xxx.xxx.xxx.xxx:8080 (the x's 
represent the device's public Internet IP address, and 8080 
represents the specified port) in your web browser's Address field. 
Management Port 
Enter the port number that will be open to outside access. The 
factory default setting is 8080. This port must be used when you 
establish a remote connection. 
UPnP 
Universal Plug and Play (UPnP) allows Windows XP and Vista to 
automatically configure the Gateway for various Internet 
applications, such as gaming and videoconferencing. If you want 
to use UPnP, keep the default, Enable. Otherwise, select Disable. 
IGMP Proxy 
Internet Group Multicast Protocol (IGMP) is used to establish 
membership in a multicast group and is commonly used for 
multicast streaming applications. For example, you may have 
Internet Protocol Television (IPTV) with multiple set-top boxes on 
the same local network. These set-top boxes have different video 
streams running simultaneously, so you should use the IGMP 
feature of the Router. 
IGMP forwarding (proxying) is a system that improves 
multicasting for LAN-side clients. If the clients support this 
option, keep the default, Enable. Otherwise, select Disable.
