This interface is a
DHCP Client This checkbox enables DHCP for the AP-5131 WAN connection.
This is useful, if the larger corporate network or Internet Service
Provider (ISP) uses DHCP.
DHCP is a protocol that includes mechanisms for IP address
allocation and delivery of host-specific configuration parameters
from a DHCP server to a host. Some of these parameters are IP
address, network mask, and gateway.
If DHCP client mode is enabled, the other WAN IP configuration
parameters are grayed out.
IP Address Specify a numerical (non DNS name) IP address for the
AP-5131 ’s WAN connection. This address defines the AP's
presence on a larger network or on the Internet.
Obtain a static (dedicated) IP address from the ISP or network
administrator. An IP address uses a series of four numbers
expressed in dot notation, for example, 190.188.12.1.
Subnet Mask Specify a subnet mask for the AP-5131 ’s WAN connection. This
number is available from the ISP for a DSL or cable-modem
connection, or from an administrator if the
AP-5131 connects to a
larger network.
A subnet mask uses a series of four numbers expressed in dot
notation (similar to an IP address). For example, 255.255.255.0 is a
valid subnet mask.
Default Gateway Specify the gateway address for the AP-5131 ’s WAN connection.
The ISP or a network administrator provides this address.
Primary DNS Server Specify the address of a primary Domain Name System (DNS)
server. The ISP or a network administrator provides this address.
A DNS server translates a domain name (for example,
www.symboltech.com) into an IP address that networks can use.
Secondary DNS
Server Specify the address of a secondary DNS server if one is used. A
secondary address is recommended if the primary DNS server goes
down.
