Text Description
IP address: The LAN IP address of the Ericsson W3x.
Subnet mask: The subnet mask, which determines the range of IP
addresses on the subnet.
The LAN IP address and subnet mask can be changed, but before you do
this, consider the following:
• Make sure that the new address is not included in the DHCP server IP
address range, displayed in the “DHCP Server” section. The default
range is 192.168.1.2 – 192.168.1.100.
• Make sure that the DHCP server IP address range is included in the
new subnet. If you want to change the subnet not to include the DHCP
IP address range, you first have to disable the DHCP server.
• If port forwarding rules have been configured, those settings have to be
removed before changing the IP address or subnet mask. For
information, see section 3.7.3 – Port Forwarding.
To change the LAN IP address or subnet mask of the Ericsson W3x, type
the new values in the corresponding fields and click
Apply to save the
settings.
Note: If you change the LAN IP address while connected to the WUI, you
will be disconnected. You have to redirect the web browser to the
new address in order to confirm the new settings. Type the new
LAN IP address in the Address (URL) field and press Enter.
3.5.2 DHCP Server
The Ericsson W3x incorporates a DHCP (Dynamic Host Configuration
Protocol) server which dynamically assigns IP addresses to devices on the
LAN/WLAN whenever they are switched on. The DHCP server also puts
the hostname, supplied by the client DHCP request, in the local DNS
(Domain Name System/Service) proxy.
The DNS proxy contains a small database of local host names and
addresses supplied by client DHCP requests. In addition it also caches
requests to remote DNS servers.
The following configuration options are displayed in the “DHCP server”
section on the LAN page:
