NAME

       xt - tc iptables action

SYNOPSIS

       tc ... action xt -j TARGET [ TARGET_OPTS ]

DESCRIPTION

       The xt action allows to call arbitrary iptables targets for packets matching the filter this action is attached to.

OPTIONS

       -j TARGET [ TARGET_OPTS ]
              Perform a jump to the given iptables target, optionally passing any target specific options in TARGET_OPTS.

EXAMPLES

       The  following  will  attach a u32 filter to the ingress qdisc matching ICMP replies and using the xt action to make the kernel yell 'PONG'
       each time:

              tc qdisc add dev eth0 ingress
              tc filter add dev eth0 parent ffff: proto ip u32 
                   match ip protocol 1 0xff 
                   match ip icmp_type 0 0xff 
                   action xt -j LOG --log-prefix PONG
