Setting up a Dialling Filter
The dialling filter can restrict the network traffic which could trigger a connection
establishment. All packets with external destination initiate a connection
establishment without dialling filter. If the dialling filter is enabled, only the packets,
which are permitted by the rules, can initiate a connection establishment.
Configuration via 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)
interface".
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
destination 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
the section "These data packets are allowed to initiate a Dial-Out" the
checkbox in the column "active". Click on "OK" to confirm the settings.
In order to delete one or more rules, check in the section "These data
packets are allowed to initiate a Dial-Out" the checkbox in the column
"delete". Click on "OK" to confirm the settings.
This function is not effective, if the LAN ext interface is configured for
a PPPoA connection.
