firehol-classify — classify traffic for traffic shaping tools


classify class [rule-params]


The classify helper command puts matching traffic into the specified traffic shaping class.

The class is a class as used by iptables(8) and tc(8) (e.g. MAJOR:MINOR).

The rule-params define a set of rule parameters to match the traffic that is to be classified. See firehol-params(5) for more details.

Any classify commands will affect all traffic matched. They must be declared before the first router or interface.


# Put all smtp traffic leaving via eth1 in class 1:1
classify 1:1 outface eth1 proto tcp dport 25
