12.5.3 Set up a Periodical Dial-out Connection Setup
The MoRoS GPRS 1.3 can establish and terminate the previously configured dial-out
connection time-controlled. The dial-out connection is established and terminated daily
at a certain time.
This function will trigger individual events; no blocking time or similar is defined. Exam-
ple: If a logout is defined for 2 pm and an automatic login at 4 pm, other events within
this period could also trigger a connection setup (dial-out), e.g. a simple packet according
to the dialing filter. The connection is also automatically terminated after an automatic
log, if the configured "Idle time" has expired, for example.
Configuration with the web interface
To establish a connection daily at a certain time, activate the checkbox "Estab-
lish a connection daily at" in the menu "Dial-out" (Figure 14, page 35, above,
position 14) and enter a time for the connection setup in the entry fields for
hours and minutes.
To terminate a connection daily at a certain time, activate the checkbox "Ter-
minate a connection daily at" in the menu "Dial-out" (Figure 14, page 35,
above, position 14) and enter a time for the termination of the connection in
the entry fields for hours and minutes.
Save the settings, by clicking "OK" (Figure 14, Page 35, above, Position 10).
12.5.4 Setting up a Dialing Filter
To avoid unnecessary costs due to undesired dial-out events, a dialing filter may be acti-
vated as an option. With this dialing filter, the network traffic which could trigger a dial-
out event can be restricted. After a dial-out connection is established, however, all par-
ticipants in the network may access the dial-out connection and transmit IP data.
Certain ports or IP addresses may be authorized or forbidden. For example, if a partici-
pant is allowed to trigger the dial-out connection using a specific IP address, then all
other IP addresses are automatically blocked for triggering a connection, which have not
been specifically permitted. If by mistake a port or an address are declared both allowed
and forbidden, then the MoRoS GPRS 1.3 will remove the entries for the forbidden ports
and addresses, which intersect with allowed entries, during the saving process. The al-
lowed ports will be maintained.
Configuration with the web interface
To activate the dialing filter, mark the checkbox "Activate dialing filter" (Figure
14, page 35 above, position 12).
To only allow connections from individual ports, enter the allowed ports in
the field "Packets from this port may initiate a connection" (Figure 14, page
35, above, Position 9). As an alternative, you may also exclude certain ports by
entering port numbers in the fields of "Packets from these ports may not initi-
ate a connection". Analogously, you may allow or forbid connections to cer-
tain destination ports.
To only allow connections from individual IP addresses, enter the allowed IP
addresses in the field "These computers may initiate a connection" (Figure 14,
