### Basics 

DEV=eth0
IP=192.168.1.4

LINERATE=2mbit
LOWRATE=8kbps

TC=/sbin/tc


### Rules - throttle SSH on ext_int

$TC qdisc del dev $DEV root

$TC qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth $LINERATE
$TC qdisc add dev $DEV parent 1: classid 1:1 cbq rate $LOWRATE allow 1500 prio 5 bounded isolated

$TC filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip sport 22 0xFFFF flowid 1:1
