Setting up a Dialling Filter
The dialling filter can restrict the network traffic which could trigger a dial-out connec-
tion establishment. All packets with external destination initiate a connection estab-
lishment without dialling filter. If the dialling filter is enabled, only the packets, which
are permitted by the rules, can initiate a connection establishment.
