xt - tc iptables action


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

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

Perform a jump to the given iptables target, optionally passing any target specific options in TARGET_OPTS.

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
