MoRoS GPRS 2.1 PRO Functions
12.3.4 Creating or Deleting a Firewall Rule
The MoRoS GPRS 2.1 PRO provides a firewall for dial-in connections. A firewall is
used to prevent unauthorized data traffic. The logic of the firewall states that any
data traffic is forbidden, which is not explicitly permitted through a rule.
Define here, which connections are permitted by the MoRoS GPRS 2.1 PRO. If you
enable the firewall for the connection type "Dial-in", only connections are possible,
which are allowed by the firewall rules. All other connections will be blocked.
Configuration with the web interface
In order to enable the firewall for dial-in connections, check in the menu
"Dial-In" on the page "Firewall" the checkbox "Activate firewall for Dial-In
connections".
In order to create a rule for an allowed IP connection, proceed as follows.
Select in the menu "Dial-In" on the page "Firewall" in the drop-down list
"Data direction" a data direction for the rule.
Define the protocol of the permitted connection in the drop-down list
"Protocol".
You can also make sure that the rule is exclusively applied to a particular
dial-in user. Select the according dial-in user name in the dropdown list
"Dial-In user name".
Enter the further specifications of the connections permitted by the Mo-
RoS GPRS 2.1 PRO into the entry fields "Source IP address", "Destination
IP address" and "Destination port". Only rules can be created, which are
not valid for individual machines (hosts), but for whole networks. In this
case, the net mask must be entered following the "/".
Save your settings by clicking "OK".
In order to disable firewall rules temporarily, uncheck in the menu "Dial-
In" on the page "Firewall" the check box in the column "Active" in the
firewall rule overview. Click on "OK" to confirm the settings.
In order to delete one or more rules, check the checkbox in the column
"delete" in the firewall rule overview. Click on "OK" to confirm the set-
tings.
