3.4.4. DHCP Server
3.4.4.1. Basic
Fig. 37. Basic DHCP server settings.
The WIASA can automatically assign IP addresses to client computers by DHCP. In this section of
the management page, you can specify the
Default gateway
,
Subnet mask
,
Primary DNS server
,
and
Secondary DNS server
settings that will be sent to a client at its request. Additionally, you can
specify the first IP address that will be assigned to the clients and the number of allocateable IP ad-
dresses.
In most cases,
Default gateway
and
Primary DNS server
should be set to the IP address of the WI-
ASA’s LAN interfaces (e.g., the default LAN IP address is
192.168.0.1
), and
Subnet mask
is set to
255.255.255.0
.
NOTE:
There should be only
one
DHCP server on the LAN; otherwise, DHCP would not work prop-
erly. If there is already a DHCP server on the LAN, disable the DHCP server functionality of the
WIASA.
3.4.4.2. Static DHCP Mappings
Fig. 38. Static DHCP mappings.
IP addresses of servers are often static so that clients could always locate the servers by the static IP
addresses. By
Static DHCP Mappings
, you can ensure that a host will get the same IP address when
