Configuring the MoRoS Modem - ISDN 1.3 Proxy Server

The MoRoS Modem - ISDN 1.3 provides a proxy server. It does not serve as a cache for
frequently accessed websites. It is used to delay the connection timeouts for dialing con-
nections that load slowly (e.g. via modem) and to filter undesired URLs. (e.g.
www.xyz.xx).

The proxy supports the HTTP and HTTPS protocols.

Configuration with the web interface

To switch the proxy server of the MoRoS Modem - ISDN 1.3 on, activate the
checkbox "Activate proxy server" in the menu "System" on the page "Proxy"
(Figure 27, page 42 above, position 1).

In the entry field "Proxy server port" (Figure 27, page 42 above, position 2), en-
ter the port, which you want to use to access the proxy server from the inter-
nal network at the IP address of the MoRoS Modem - ISDN 1.3.

To terminate connections after a certain time, which seem to be inactive, you
can adjust the time in the entry field "Timeout for inactive connections"
(Figure 27, page 42 above, position 3).

To avoid overloading the MoRoS Modem - ISDN 1.3, you can restrict the num-
ber of clients which can connect to the MoRoS Modem - ISDN 1.3 at the same
time. Enter the maximum number of simultaneously authorized clients in the
entry field "Maximum number of authorized clients (Figure 27, page 42 above,
position 4).

To increase the availability of the proxy you can define a minimum number of
proxy server processes. Enter the desired number of proxy server processes
that are always running on the MoRoS Modem - ISDN 1.3 into the entry field
"Minimum number of free proxy servers".

To avoid overloading the MoRoS Modem - ISDN 1.3 with proxy requests, you
can define a maximum number of proxy server processes. For each client re-
quest, an individual proxy server process is started on the MoRoS Modem -
ISDN 1.3. Enter the desired maximum number of simultaneous proxy server
processes in the entry field "Maximum number of free proxy servers" (Figure
27, page 42 above, position 5). If more requests are received than available as
proxy servers, the additional requests are rejected.

12.8.2

Set up an URL Filter

With the help of the URL filter, the proxy of the MoRoS Modem - ISDN 1.3 can restrict
possible URLs, which can be accessed by computers from the internal network of the
MoRoS Modem - ISDN 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 activated. Without the firewall, the access to any URLs would be
possible just by bypassing the proxy.
