the appliance, adjust the DHCP IP address range appropriately. See
the DHCP IP address range"
Table 4-1 shows the default start and end IP addresses for each model. The
default range is based on the recommended number of concurrent clients for
each model. The number of clients you can support may vary depending on your
traffic characteristics.

The DHCP server only supports class C networks. Class C networks have
addresses from 192.0.0.0 through 223.255.255.0. The network number is the
first three octets, being from 192.0.0 through 223.255.255. Each class C network
can have one octet worth of hosts.
You can place the appliance in any class network, but the DHCP server does not
support this.
If you have a mix of clients that use DHCP and static IP addresses, the static IP
addresses must be outside the range of DHCP IP addresses. Also, you may want
to assign static IP addresses to some services. For example, if you have a Web
server on your site, you want to assign it a static address.
The DHCP server in the appliance is enabled by default. If you disable the DHCP
server, each client connecting to the LAN must be assigned an IP address that is
in the range. If you enable the roaming on the appliance as a secondary wireless
access point, the DHCP server is disabled.
To configure the appliance as a DHCP server
You can enable or disable DHCP, and you can set the range of IP addresses that
the appliance allocates to the clients.
