AP-7131 Access Point: Installation Guide

4. Optionally enter the IP address of the server used to provide system time to the AP-7131

within the Time Server field.

Once the IP address is entered, the AP-7131’s Network Time Protocol (NTP) functionality is

engaged automatically. Refer to the AP-7131 Product Reference Guide for information on

defining alternate time servers and setting a synchronization interval for the AP-7131 to

adjust its displayed time.

5. Click the WAN tab to set a minimum set of parameters for using the WAN interface.

a. Select the Enable WAN Interface checkbox to enable a connection between the

AP-7131 and a larger network or outside world through the WAN port. Disable this

option to effectively isolate the AP-7131’s WAN connection. No connections to a larger

network or the Internet will be possible. MUs cannot communicate beyond the

configured subnets.

b. Select the This Interface is a DHCP Client checkbox to enable DHCP for the AP-7131

WAN connection. This is useful, if the target 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.

c. Specify an IP address for the AP-7131’s WAN connection. An IP address uses a series

of four numbers expressed in dot notation, for example, 190.188.12.1.

d. Specify a Subnet Mask for the AP-7131’s WAN connection. This number is available

from the ISP for a DSL or cable-modem connection, or from an administrator if the

AP-7131 connects to a larger network. A subnet mask uses a series of four numbers

expressed in dot notation. For example, 255.255.255.0 is a valid subnet mask.

e. Specify a Default Gateway address for the AP-7131’s WAN connection. The ISP or a

network administrator provides this address.

f. Specify the address of a Primary DNS Server. The ISP or a network administrator

provides this address.

6. Optionally, use the Enable PPP over Ethernet checkbox to enable Point-to-Point over

Ethernet (PPPoE) for a high-speed connection that supports this protocol. Most DSL

providers are currently using or deploying this protocol. PPPoE is a data-link protocol for

dialup connections. PPPoE will allow the AP-7131 to use a broadband modem (DSL, cable

modem, etc.) for access to high-speed data networks.

a. Select the Keep Alive checkbox to enable occasional communications over the WAN

port even when client communications to the WAN are idle. Some ISPs terminate

inactive connections, while others do not. In either case, enabling Keep-Alive maintains
