Select
Static
if you would like to set up a
static IP address for your phone. A static IP
address is useful, for example, if port for-
warding or a DMZ is set up on the router
for the phone.
The following fields are displayed when
you select
IP address type
=
Static
:
IP address
Enter an IP address for you phone. This
IP address allows it to be reached by
other subscribers in your local network
(e.g. PC).
192.168.2.2 has been preset.
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 –
192.168.255.254 with
Subnet mask
255.255.255.0. The subnet mask
determines that the first three parts
of the IP address must be identical
for 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. It must also not be used by
another device on the router.
If necessary, check the settings on the
router.
Subnet mask
Enter the subnet mask for your device's
IP address. For 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
supplied.
Default gateway
Enter the IP address for the standard
gateway, by means of which the local
network is connected with the Internet.
This is generally the local (private) IP
address for your router (e.g.
192.168.2.1). Your phone requires this
information to be able to access the
Internet.
192.168.2.1 has been preset.
Preferred DNS server
Enter the IP address for the preferred
DNS server. DNS (Domain Name Sys-
tem) allows you to assign public IP
addresses to symbolic names.
The DNS server is required to convert
the DNS name into the IP address when
connection is being established to a
server.
You can specify your router's IP address
here. The router forwards phone
address requests to its DNS server.
192.168.2.1 has been preset.
Alternate DNS server
(optional)
Enter the IP address for the alternative
DNS server that should be used in situ-
ations where the preferred DNS server
cannot be reached.

Allow access from other networks
The default setting for you phone is that
you can only access your phone's Web
configurator via a PC that is in the same
local network as your phone. The subnet
mask of the PC must match that of the
phone.
You can also allow access from PCs in
other networks.

In the
Remote Management
area, activate
the option
Yes
to permit access from
other networks.
To deactivate remote access, click on
the
No
option. Access is then limited to
PCs in your own local network.
Warning:
Expansion of access entitlement to other net-
works increases the risk of unauthorised
access.
It is therefore recommended to deactivate
remote access again if you no longer need it.
