.B %any

To limit the connection to a specific range of hosts, a range (
.BR 10.1.0.0-10.2.255.255
) or a subnet (
.BR 10.1.0.0/16
) can be specified, and multiple addresses, ranges and subnets can be separated
by commas. While one can freely combine these items, to initiate the connection
at least one non-range/subnet is required.
Please note that with the usage of wildcards multiple connection descriptions
might match a given incoming connection attempt. The most specific description
is used in that case.
