[ip-range]
The [ip-range] firewall script field specifies the range of IP addresses and ports to match. The range
can be specified in one of several ways. The basic syntax is:
i p- r ange=“ al l ” | “ f r om” i p- obj ect “ t o” i p- obj ect [ f l ags] [ i cmp]
where ip-object is an IP address specification. For full details of the syntax with examples, see
