NAME

       sanewall-mark - mark traffic for traffic shaping tools

SYNOPSIS

       mark value chain [rule-params]

DESCRIPTION

       The mark helper command sets a mark on packets that can be matched by traffic shaping
       tools for controlling the traffic.

           Note
           To set a mark on whole connections, see connmark config helper: sanewall-connmark(5).
           There is also a mark parameter which allows matching marks within individual rules
           (see optional rule parameters: sanewall-rule-params(5)).

       The value is the mark value to set (a 32 bit integer).

       The chain will be used to find traffic to mark. It can be any of the iptables built in
       chains belonging to the mangle table. The chain names are: INPUT, FORWARD, OUTPUT,
       PREROUTING and POSTROUTING. The names are case-sensitive.

       The rule-params define a set of rule parameters to match the traffic that is to be marked
       within the chosen chain. See optional rule parameters: sanewall-rule-params(5) for more
       details.

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

           Note
           If you want to do policy based routing based on iptables marks, you will need to
           disable the Root Path Filtering on the interfaces involved (rp_filter in sysctl).

EXAMPLES

           # mark with 1, packets sent by the local machine
           mark 1 OUTPUT

           # mark with 2, packets routed by the local machine
           mark 2 FORWARD

           # mark with 3, packets routed by the local machine, sent from
           #              192.0.2.2 destined for port TCP/25 of 198.51.100.1
           mark 3 FORWARD proto tcp dport 25 dst 198.51.100.1 src 192.0.2.2
