IP Address: This is the address used by the router for local area network communication. Changes to this parameter may
require a restart to computers on this network.
Each network must have a distinct IP address. Most users will want an address from one of the following private IP
ranges:
10.0.0.1 - 10.255.255.1
172.16.0.1 - 172.31.255.1
192.168.0.1 - 192.168.255.1
NOTE: The final number does not have to be 1, but it is a simple, logical convention for routers that leaves higher numbers free for other devices.
Netmask: (Default: 255.255.255.0) The netmask controls how many IP addresses can be used in this network. The
default value allows for 254 IP addresses, which is enough in most cases.
Routing Mode: (Default: NAT) Each network can use a unique routing mode to connect to the internet and other local
networks. NAT is desirable for most configurations. Select from the following options in the dropdown list:
NAT: Network Address Translation hides private IP addresses behind the router's IP address. This is the simplest
and most common choice for users, because NAT does the translation work for you.
Standard: NAT-less routing. If you select Standard, you must separately configure your IP addresses so that they
will be publically accessible. Typically you will not select this option unless you have a specific reason to bypass
NAT.
IP Passthrough: IP Passthrough passes the IP address given by the modem WAN through the router. The
Ethernet port must be in LAN mode or Disabled mode, and VPN and GRE must be disabled.
Disabled: Disable this network.
