The IP addresses that can be assigned to
LAN/WLAN clients are collected from a
predefined range of available IP addresses.
The preconfigured range – from 92.168.1.2 to
192.168.1.100 – is suitable for most local
networks.

The DHCP server uses the concept of a
“lease”, that is the amount of time that a given
IP address will be valid for a specific device. If
the lease time expires and the device is still
connected, the lease is automatically renewed.
Lease Time [sec]
The preconfigured lease time is 7200 seconds
(2 hours) and a valid value must be within the
range 60 and 2147483647 seconds.
Note: If you want to configure a connected device with a static IP
address, make sure that the address is outside the DHCP server IP
address range.
Before changing any of the DHCP server settings, read the following:
• The DHCP server IP address range has to be on the same subnet as
the Ericsson W21 LAN IP address.
• The DHCP server IP address range must not include the Ericsson W21
LAN IP address.
• If port forwarding rules have been created, those settings have to be
removed before changing the DHCP server IP address range. For
more information, see section
– Port Forwarding.
To change the DHCP server settings, type the new values in the
corresponding fields and click
Apply
to save the settings.
