13 Set the following DHCP and Static IP Address/Subnet information for the LAN 
interface:
●
Use DHCP - Select the checkbox to enable an automatic network address 
configuration using the Access Point’s DHCP server. An Altitude 4521 Series Access 
Point does not have an onboard DHCP server and an external DHCP server must be 
utilized.
●
Static IP Address/Subnet - Enter an IP Address and a subnet for the Access Point's 
LAN interface. If Use DHCP is selected, this field is not available. When selecting this 
option, define the following DHCP Server and Domain Name Server (DNS) resources, 
as those fields will become enabled on the bottom portion of the screen.
- Use on-board DHCP server to assign IP addresses to wireless clients -Select the 
checkbox to enable the Access Point’s DHCP server to provide IP and DNS 
information to clients on the LAN interface.
- Range - Enter a starting and ending IP Address range for client assignments on the 
Access Point's LAN interface. Avoid assigning IP addresses from x.x.x.1 - x.x.x.10 
and x.x.x.255, as they are often reserved for standard network services. This is a 
required parameter.
- Default Gateway - Define a default gateway address for use with the default 
gateway. This is a required parameter.
●
DNS Forwarding - Select this option to allow a DNS server to translate domain names 
into IP addresses. If this option is not selected, a primary and secondary DNS 
resource must be specified. DNS forwarding is useful when a request for a domain 
name is made but the DNS server, responsible for converting the name into its 
corresponding IP address, cannot locate the matching IP address. 
- Primary DNS - Enter an IP Address for the main Domain Name Server providing 
DNS services for the Access Point's LAN interface.
- Secondary DNS - Enter an IP Address for the backup Domain Name Server 
providing DNS services for the Access Point's LAN interface
