N4100 User’s Guide

Traditionally, you must set the IP addresses and the subnet masks of a computer 
and the N4100 to be in the same subnet to allow the computer to access the 
Internet (through the N4100). 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 N4100. 

With the iPnP feature and NAT enabled, the N4100 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 
N4100 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 N4100 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 
N4100 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 N4100 are not in the same subnet. 

Figure 30   iPnP Example

The iPnP 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 N4100's IP address. 

Note: You must enable NAT to use the iPnP feature.
