Compex Systems 802.11N - Manual (Page 66)

Bridge IP Address:
The device can be set for static IP or can be set to obtain an IP address from the DHCP
server it is connected to. One of the IP assignment modes must be selected:
DHCP : choose this option to assign the dynamic IP address, Gateway and DNS address by the
local DHCP server.
STATIC : choose this option to assign the static IP settings for the bridge interface.
IP Address: enter the IP address of the device while Static Bridge IP Address mode is selected.
This IP will be used for the device management purposes.
IP Address and Netmask settings should consist with the address space of the network segment
where device resides. If the device IP settings and administrator PC (which is connected to the
device in wired or wireless way) IP settings will use different address space, the device will
become unreachable.
Netmask: This is a value which when expanded into binary provides a mapping to define which
portions of IP address groups can be classified as host devices and network devices.
Netmask defines the address space of the network segment where device
resides. 255.255.255.0 (or /24) Netmask is commonly used among many C Class IP networks.
Gateway IP: Typically, this is the IP address of the host router which provides the point of
connection to the internet. This can be a DSL modem, Cable modem, or a WISP gateway router.
Device will direct the packets of data to the gateway if the destination host is not within the local
network. Gateway IP address should be from same address space (on same network segment) as
the device.
Primary/Secondary DNS IP:
The Domain Name System (DNS) is an internet "phone book" which translates domain
names to IP addresses. These fields identify the server IP addresses of where the device
looks for the translation source.
Primary DNS server IP address should be specified for the device management purposes.
Secondary DNS server IP address is optional. It is used as the fail-over in case the primary DNS
server will become unresponsive.
DHCP Fallback IP:
In case the Bridge is placed in Dynamic IP Address mode (DHCP) and is unable to obtain an IP
address from a valid DHCP server, it will fall back to the static IP address listed here. In case the
IP settings of the devices are unknown, they can be access with the help of the UConfig utility.
The UConfig Utility should be started on the administrator PC which resides on
the same network segment as the device.
Device will return to the default IP configuration (192.168.168.1/255.255.255.0)
if the Reset to defaults routine is initiated.
