Subcommands and parameters
filter add name
The filter add subcommand adds filter expressions (FEs) to a list that is stored in prioritized order, with
the first position assigned the highest-priority filter expression. Incoming and outgoing datagrams are
checked against the entry in the highest-priority position first.
Several options to the filter add subcommand exist. Options, variables, and parameters are described
next. It is important to note that one of the following options is required:
-s, -d, -p, -l, -i, or -f
If an option has no default, and is not specified in the filter entry, no match is attempted for that field.
filter add name
name—A 1 to 6 character ASCII identifier chosen by the user to easily reference filter expressions. Each
filter expression must have a unique name. Names beginning with a "$" are reserved for system use
(as IP "firewall" filter names).
