12.5.7 Setting up a Dialling Filter
The dialling filter can restrict the network traffic which could trigger a dial-out con-
nection establishment. All packets with external destination initiate a connection es-
tablishment without dialling filter. If the dialling filter is enabled, only the packets,
which are permitted by the rules, can initiate a connection establishment.
Configuration with the web interface
In order to enable the dialling filter, check in the menu "LAN (ext)" on the
page "Dial filters" the checkbox "Activate Dial-Out filters for LAN (ext) in-
terface".
In order to permit connections via a certain protocol, select in the field
"Create new rule" the permitted protocol in the drop-down list "Protocol".
In order to permit connections of certain IP addresses, enter the permitted
source IP address into the entry field "Source IP address".
In order to permit connections to certain ports, enter the permitted desti-
nation port into the entry field "Destination port".
In order to permit connections to certain IP addresses, enter the permitted
destination IP address into the entry field "Destination IP address".
Optionally, you can use the checkbox "Allow DNS requests from source IP
address to initiate a connection" to allow that DNS requests of the defined
source IP addresses are allowed to initiate a connection establishment.
Save your settings by clicking "OK".
In order to disable individual dialling filter rules temporarily, uncheck in
