Allowing Access From Other Networks - Siemens Gigaset DX800A all in one Setup & User Manual

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 convert the DNS name into the IP address when a 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 is the default.
Alternate DNS server (optional)
Enter the IP address for the alternate DNS server that should be used in situa-
tions where the preferred DNS server cannot be reached.

After you have changed the IP configuration, the base is rebooted. You are logged
off the Web configurator. The Login Web page is displayed after the reboot.

Allowing access from other networks

The default setting for your phone only allows you to access your phone's Web con-
figurator 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.
Warning
Authorising access from other networks increases the risk of unauthorised
access. It is therefore recommended that you deactivate remote access if you no
longer require it.
¤
Open the Settings
Remote Management area
¤
Select Yes to authorise access from other networks.
To deactivate remote access, select No. Access is then limited to PCs in your own
local network.
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 "out-
side" to Port 80 (default port) of the phone. Be sure to 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.
