Network Settings
The Network Settings page allows you to set a number of local IP options on the gateway.
IPv4 Address
You may permanently assign the IP address of the gateway by specifying it in this field.
Doing so will disable BOOTP/DHCP.
If you want to re-enable BOOTP/DHCP, you can do so by setting the IP address to 0.0.0.0, or
by restoring the default configuration (see the section called Restore Factory Defaults).
IPv4 Netmask
Every IP address contains two pieces of information: the network number and the host
number. A network number is assigned to each local area network and is shared by all the
network devices on that network. Each network device, or “host”, is assigned a unique host
number. The IP netmask defines which portion of an IP address contains the network
number, and which portion contains the host number. The default netmask depends on the
“class” of the IP address that you are using. These classes are defined in Table 2-1.
