AP-5131 Access Point: Installation Guide
28
inactive connections, while others do not. In either case, enabling Keep-Alive maintains
the WAN connection, even when there is no traffic. If the ISP drops the connection after
the idle time, the AP-5131 automatically reestablishes the connection to the ISP.
b. Specify a Username entered when connecting to the ISP. When the Internet session
begins, the ISP authenticates the username.
c. Specify a Password entered when connecting to the ISP. When the Internet session
starts, the ISP authenticates the password.
7. Click the LAN tab to set a minimum set of parameters to use the AP-5131 LAN interface.
a. Select the Enable LAN Interface checkbox to forward data traffic over the AP-5131
LAN connection. The LAN connection is enabled by default.
b. Use the This Interface drop-down menu to specify how network address information
is defined over the AP-5131’s LAN connection. Select DHCP Client if the larger
corporate network 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.
Select DHCP Server to use the AP-5131 as a DHCP server over the LAN connection.
c. Enter the network-assigned IP Address of the AP-5131.
d. The Subnet Mask defines the size of the subnet. The first two sets of numbers specify
the network domain, the next set specifies the subset of hosts within a larger network.
These values help divide a network into subnetworks and simplify routing and data
transmission.
e. Enter a Default Gateway to define the IP address of a router the AP-5131 uses on the
Ethernet as its default gateway.
f. Enter the Primary DNS Server IP address.
g. If using DHCP Server, use the Address Assignment Range parameter to specify a
range of IP address reserved for mapping clients to IP addresses. If a manually (static)
mapped IP address is within the IP address range specified, that IP address could still be
assigned to another client. To avoid this, ensure all statically mapped IP addresses are
outside of the IP address range assigned to the DHCP server.
NOTE For additional AP-5131 WAN and LAN port configuration options, as well
as radio, WLAN and Quality of Service (QoS) options, refer to the AP-5131
Product Reference Guide. The guide is on the CD-ROM shipped with the
AP-5131, or can be found at
