IP Configuration
Make the necessary settings for operating your phone in your local network and to connect
it to the Internet. For more detailed explanations of the individual components/terms, see
the glossary (page 134).
The base station phone and router are set by default so that there is a connection between
them. You only have to change the IP configuration for your phone in exceptional circum-
stances, e.g. if you have configured port forwarding to the phone for the router, or if you
had to deactivate the router's DHCP server. In this case you need to assign the phone a fixed
IP address.
Assigning the IP address

Select
Obtained automatically
if you want your phone to be assigned a dynamic IP address by
a DHCP server in your local network. No further settings are necessary for the local net-
work.
Select
Static
if you would like to set up a static IP address for your phone. A fixed IP address
makes sense, for example, if port forwarding is set up on the router for the phone
The following fields are displayed when you select

:
IP address
Enter an IP address for your phone. This IP address allows it to be reached by other sub-
scribers in your local network (e.g. PC).
The default is 192.168.1.2.
Please note the following:
– The IP address must be from the address block for private use that is used in the
router. This is generally in the range 192.168.0.1 – 192.168.255.253 with
Subnet
mask
255.255.255.0. The subnet mask determines that the first three parts of the IP
address must be identical for routers and all subscribers in your LAN.
– The static IP address must not belong to the address block (IP pool range) that is
reserved for the DHCP server of the base station router. It must also not be being used
by another device that is connected to the base station via the LAN connection
(directly or via a hub/switch).
If necessary, check the setting at the base station router (page 79).
Subnet mask
Enter the subnet mask that you have set at your base station router (page 79).
Default gateway
Enter the private IP address for the base station router (page 79). Your base station
phone requires this information to be able to access the Internet.
The default is 192.168.1.1.
