Preferred DNS server
Enter the IP address for the preferred DNS server. DNS (Domain Name System) allows
you to assign public IP addresses to symbolic names. The DNS server is required to con-
vert 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 situations
where the preferred DNS server cannot be reached.
Click Set to save the changes.
Click Cancel to reject the changes.
Allowing access from other networks
The default setting for your phone is set such 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.
¤
Open the following Web page: Settings
¢
IP Configuration .
¤
In the Remote Management area, activate the Yes option to permit access from other net-
works.
To deactivate remote access, click
No . Access is then limited to PCs in your own local net-
work.
Access to the Web configurator services from other networks is only possible if your router
is set accordingly. The router must pass on the service requests from "outside" to Port 80
(default port) of the phone. Please also read the user guide for your router.
To establish a connection, the public IP address or the DNS name of the router and, where
applicable, the port number on the router must be indicated in the Web browser of the
remote PC.
Warning:
Expansion of access entitlement to other networks increases the risk of unauthorised access.
It is therefore recommended that you deactivate remote access again if you no longer require it.
