NXA-WAP250G 802.11b/g Wireless Access Point

The displayed items on this page can be described as follows:

 DHCP Client Setting – Enables the NXA-WAP250G to automatically obtain an IP address

from a DHCP server. If a response is not received from the DHCP server, the NXA-WAP250G

uses the fixed IP settings as configured on this page. When set to disabled, a static IP address

can be manually configured.

 Static IP Address – The IP address of the NXA-WAP250G. Valid IP addresses consist of four

decimal numbers, 0 to 255, separated by periods.

 Subnet Mask – The mask that identifies the host address bits used for routing to specific

subnets.

 Default Gateway – The default gateway is the IP address of the router for the NXA-

WAP250G, which is used if the requested destination address is not on the local subnet. If you

have management stations located on another subnet, type the IP address of the default

gateway router in the text field provided. Otherwise, leave the address as all zeros (0.0.0.0).

 DNS IP Address – The IP address of a Domain Name Server on the network. A DNS maps

numerical IP addresses to domain names and can be used to identify network hosts by familiar

names instead of the IP addresses.

If you have a DNS server located on the local network, type the IP address in the text

field provided. Otherwise, leave the address as all zeros (0.0.0.0).

DHCP Server/NAT

The NXA-WAP250G includes a Dynamic Host Configuration Protocol (DHCP) server that can assign

temporary IP addresses to wireless clients requesting the service (FIG. 27).

Addresses are assigned to clients from a common address pool configured on the NXA-WAP250G.

Configure an address pool by specifying start and end IP addresses. Be sure not to include the NXA-

WAP250G's IP address in the address pool range.

Network Address Translation (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 Ethernet port. When enabled, the NXA-WAP250G's

wireless interface uses the NAT IP settings to access the Ethernet network.

When the DHCP server is enabled, NAT is also enabled.
