'fw' tam prave mam.

cely postup:
-----------
znackovani:
/sbin/ipchains -A input -s 192.168.1.115 -m 773

cbq:
--
1. tc qdisc del dev eth0 root
2. tc qdisc add dev eth0 root handle 1 cbq bandwidth 100Mbit avpkt 1000 \
	cell 8
3. tc class change dev eth0 root cbq weight 10Mbit allot 1514
--
4. tc qdisc del dev eth1 root
5. tc qdisc add dev eth1 root handle 1 cbq bandwidth 10Mbit avpkt 1000 \
	cell 8
6. tc class change dev eth1 root cbq weight 1Mbit allot 1514
--
7. tc class add dev eth0 parent 1: classid 1:1364 cbq bandwidth 100Mbit \
	rate 64Kbit  weight 6Kbit prio 5 allot 1514 cell 8 maxburst 20 \
	avpkt 1000 bounded
8. tc qdisc add dev eth0 parent 1:1364 handle 1364 tbf rate 64Kbit \ 
	buffer 10Kb/8 limit 15Kb mtu 1500
9. tc filter add dev eth0 parent 1:0 protocol ip prio 200 handle 773 \
	fw classid 1:1364
--
10. tc class add dev eth1 parent 1: classid 1:1464 cbq bandwidth 10Mbit \
	rate 64Kbit weight 6Kbit prio 5 allot 1514 cell 8 maxburst 20 \
	avpkt 1000 bounded
11. tc qdisc add dev eth1 parent 1:1464 handle 1464 tbf rate 64Kbit \ 
	buffer 10Kb/8 limit 15Kb mtu 1500
12. tc filter add dev eth1 parent 1:0 protocol ip prio 100 u32 match \
	ip dst 192.168.1.115 classid 1:1464  
--

na 9. radce fw preci definuji, ne?
