LAN IP Configuration
Lan 1 IP Configuration Screen
This hardware contains three Ethernet interfaces which are bridged together (similar to an Ethernet
switch). They all share the same IP addressing. This screen is used to configure IP parameters for the
entire unit.
Fields
Configure IP
Select DHCP or a static configuration. If DHCP is selected, the static-configuration is ignored.
IP Address
An IP address is a numeric identifier given to an interface. It consists of four 8-bit numbers and is
represented in a dotted notation. An example of an IP address is "192.168.0.10". An Ethernet IP address
must be unique within your network. If you are directly connected to the Internet, it must globally
unique.
This field is not used if DHCP Client has been enabled. The DHCP server will assign the IP address.
Subnet Mask
A subnet mask is a bit mask applied against the IP address. It specifies which portion of the IP address
is the subnet identifier and which portion is the host identifier. For example, many subnets have a
mask of 255.255.255.0. This means the first 24 bits of the address is the subnet identifier and the last 8
bits is the host identifier.
This field is not used if DHCP Client has been enabled. The subnet mask will be assigned by the
DHCP server.
Gateway
The Gateway specifies the address of the gateway router on the local subnet. Packets destined for a
host not on the local subnet are forwarded to the gateway router. Note that additional gateway routes
may be specified on the “Static Routes” screen.
