The Prestige supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At 
start up, the Prestige queries all directly connected networks to gather group membership. 
After that, the Prestige periodically updates this information. IP multicasting can be enabled/
disabled on the Prestige LAN and/or WAN interfaces in the web configurator (LAN; WAN). 
Select None to disable IP multicasting on these interfaces.
7.3  Any IP
Traditionally, you must set the IP addresses and the subnet masks of a computer and the 
Prestige to be in the same subnet to allow the computer to access the Internet (through the 
Prestige). In cases where your computer is required to use a static IP address in another 
network, you may need to manually configure the network settings of the computer every time 
you want to access the Internet via the Prestige. 
With the Any IP feature and NAT enabled, the Prestige allows a computer to access the 
Internet without changing the network settings (such as IP address and subnet mask) of the 
computer, when the IP addresses of the computer and the Prestige are not in the same subnet.  
Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply 
connect the computer to the Prestige and access the Internet. 
The following figure depicts a scenario where a computer is set to use a static private IP 
address in the corporate environment. In a residential house where a Prestige is installed, you 
can still use the computer to access the Internet without changing the network settings, even 
when the IP addresses of the computer and the Prestige are not in the same subnet. 
Figure 61   Any IP Example Application
The Any IP feature does not apply to a computer using either a dynamic IP address or a static 
IP address that is in the same subnet as the Prestige’s IP address.
Note: You must enable NAT to use the Any IP feature on the Prestige.
