MoRoS GPRS 1.3 Functions

number of free proxy servers".

To avoid overloading the MoRoS GPRS 1.3 with proxy requests, you can define

a maximum number of proxy server processes. For each client request, an in-

dividual proxy server process is started on the MoRoS GPRS 1.3. Enter the de-

sired maximum number of simultaneous proxy server processes in the entry

field "Maximum number of free proxy servers" (Figure 25, page 40 above, po-

sition 5). If more requests are received than available as proxy servers, the ad-

ditional requests are rejected.

Save the settings by clicking "OK" (Figure 25, page 40 above, position 7).

12.7.2 Set up an URL Filter

With the help of the URL filter, the proxy of the MoRoS GPRS 1.3 can restrict possible

URLs, which can be accessed by computers from the internal network of the MoRoS GPRS

1.3. This will allow only access to URLs which are entered in the filter list. All other URLs

are blocked. To allow access to the Internet only via the proxy, the firewall must be acti-

vated. Without the firewall, the access to any URLs would be possible just by bypassing

the proxy.

At the clients (e.g. a web browser on a PC), which establish connections via the proxy, the

IP address of the proxy must be defined.

Configuration with the web interface

To switch the URL filter on, activate the checkbox "Activate filter" (Figure 25,

page 40 above, position 9).

To enter an authorized URL which is accessible from the internal network, en-

ter the desired URL in the entry fields "Authorized URLs" (Figure 25, page 40

above, position 8).

To delete an URL from the list, delete the text of the URL from the list (Figure

25, page 40 above, position 8).

Save the settings by clicking "OK" (Figure 25, page 40 above, position 7).

12.8 Inputs

12.8.1 Query the State of the Inputs

opened when there is no connection with GND. The states of the two inputs can be que-

ried via the web interface.
