Initial Configuration

NXA-WAP250G 802.11b/g Wireless Access Point

3. Network Setting – Sets the NXA-WAP250G’s IP address assignment method and configures the

local Dynamic Host Configuration Protocol (DHCP) server and Network Address Translation

(NAT) settings (FIG. 8).

There are three basic methods for configuring the NXA-WAP250G’s IP address:

 Dynamic IP — The IP address is assigned automatically from a home gateway router or other

device that has a DHCP server feature.

 PPPoE — The IP address is assigned automatically from an Internet service provider (ISP)

through an ADSL modem using Point-to-Point Protocol over Ethernet (PPPoE). If your ISP

has provided you with a user name and password, enter these in the corresponding text boxes

under PPPoE Setting.

 Static IP — The IP address is assigned manually by the user. This may be required if your

NXA-WAP250G is connected to a home gateway router or other device that does not support

a DHCP server.

If you select Static IP, enter an appropriate IP address and subnet mask that are compatible

with your existing network. If a management station exists on another network segment, then

you must enter the IP address for a Default Gateway that can route traffic between these

segments. Also enter the IP address for the Domain Name Server (DNS) to be used for host-

name to IP address resolution (FIG. 9).

DHCP Server/NAT Setting — The NXA-WAP250G includes a DHCP server that can assign

IP addresses to any wireless device. Addresses are assigned from a common address pool

configured on the NXA-WAP250G. You can configure the address pool by specifying start and

end IP addresses.

NAT is a standard method of mapping multiple “internal” IP addresses to one “external” IP

address on devices at the edge of a network. For the NXA-WAP250G, the internal (local) IP

addresses are the IP addresses assigned to wireless clients by the DHCP server, and the

external IP address is the IP address assigned to the NXA-WAP250G itself. Note that the

NXA-WAP250G IP address is always in a different subnet from the DHCP server pool. The

NXA-WAP250G uses the NAT IP settings to route traffic from the wireless interface to the

Ethernet network.

Wireless VAP #1 Setting – VAP (Virtual Access Point) #1sets the wireless Service Set Identifier

(SSID) and wireless security encryption key for the VAP#1 network.
