The P-660H-T1v3s supports IGMP version 1 (IGMP-v1), IGMP version 2 (IGMP-
v2) and IGMP version 3 (IGMP-v3). At start up, the P-660H-T1v3s queries all
directly connected networks to gather group membership. After that, the P-660H-
T1v3s periodically updates this information. IP multicasting can be enabled/
disabled on the P-660H-T1v3s LAN and/or WAN interfaces in the web configurator
(LAN; WAN). Select None to disable IP multicasting on these interfaces.
7.6.7 Any IP
Traditionally, you must set the IP addresses and the subnet masks of a computer
and the P-660H-T1v3s to be in the same subnet to allow the computer to access
the Internet (through the P-660H-T1v3s). 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 P-660H-T1v3s.
With the Any IP feature and NAT enabled, the P-660H-T1v3s 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 P-
660H-T1v3s 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
P-660H-T1v3s 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 P-
660H-T1v3s 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 P-660H-T1v3s are not in the same subnet.
