Configuring the local network
You can use the LAN configuration to define a private IP address for the router and to con-
figure the LAN DHCP server.
Defining the router's private IP address
¤
Open the following Web page: Router Settings
¢
Local Network .
You can change the IP address for the base station router on this page. The default IP
address is 192.168.1.1. This is the router's private IP address (LAN address). This is the IP
address under which the base station router can be reached on the local network. This IP
address can be freely assigned from the block of addresses that is reserved for private use.
The IP address under which the router can be reached from outside is assigned by the Inter-
net provider.
¤
If you want to assign the router a different IP address, enter it in the fields for IP Address .
We recommend using an IP address from a block that is reserved for private use. This
address block is 192.168.1.1 – 192.168.255.254.
¤
Enter the values in the fields for Subnet Mask (page 143).
For IP addresses from the address block 192.168.0.1 – 192.168.255.254 the subnet
mask 255.255.255.0 is generally used. This is preconfigured when the phone is sup-
plied. A subnet mask 255.255.255.x means that the first three parts of the IP addresses
for all devices in the router's local network (base station phone and the device con-
nected to the LAN connection) must match.
Configuring the DHCP server
The router has a DHCP server whose factory setting is active. The IP addresses for the PCs
and the phone are automatically assigned by the router, provided that DHCP is also acti-
vated on the PCs and the phone.
¤
To activate the DHCP server, select On in the DHCP Server field.
¤
If the DHCP server is active, you have to specify a block of IP addresses that the router is
to use for automatically assigning the IP addresses to the PCs. Define the First issued IP
Address
and the
Last issued IP Address
.
Applying the settings for the local network
¤
Click Set to apply the settings.
The base station router is rebooted to activate the settings. The reboot can take several
minutes (depending on the provider). Do not disconnect your base station from the PC or
the power supply during this period.
Please note:
– The address block is not allowed to contain the router's private IP address (default setting:
192.168.1.1).
– If the DHCP server for the router is activated, you can configure the network setting on the PCs so
that the option Obtain an IP address automatically is set on the PCs.
– If you deactivate the DHCP server, you have to assign the PCs a static IP address from your router's
IP address block via the network settings.
– The phone and PCs retain the dynamically assigned IP address until the router is next rebooted.
The allocation is done again each time the router is rebooted.
