Bug ID: 210303
Summary: garbage in ipf(5)
Product: Documentation
Version: Latest
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: Documentation

There is a garbage written in ipf(5)
TCP/UDP Port Matching
Having specified which protocol is being matched, it is then possible
to indicate which port numbers a packet must have in order to match the
rule. Due to port numbers being used differently to addresses, it is
therefore possible to match on them in different ways. IPFilter allows
you to use the following logical operations:
< x is true if the port number is greater than or equal to x and
less than or equal to y is true if the port number in the packet
is less than x
and the whole port range matching simply not implemented:
Additionally, there are a number of ways to specify a range of ports:
garbage:
x <> y is true if the port number is less than a and greater than y
x >< y is true if the port number is greater than x and less than y
x:y is true if the port number is greater than or equal to x and
less than or equal to y
Even the example doesn't work:
pass in proto tcp from 127.0.0.0/8 to any port = 6000:6009
It says:
syntax error error at ":", line 2
