It is often desirable to partition larger networks into a series of smaller networks that are
separated by routers (also called “gateways”). This process is called “subnetting” and is
accomplished by extending the default netmask. Some examples of common netmasks can
be found in Table 2-2.
IP Address

255.255.255.0

Table 2-2: IP Netmask Examples
If you are not using DHCP/BOOTP and your network uses subnets (or supernets), you can
override the default net mask by specifying it in this field. Once you click the "Save IP
Address/Netmask" button these parameters will be saved. They will take effect on the next
reboot (see the Reset/Reboot section).
Default Gateway
The default gateway may be specified either on this page or the IP Routing page.
Ethernet MTU
Specifies the maximum size of packets sent on the local area network – the Maximum
Transmit Unit or MTU.
