Why would you assign traffic at B if it doesn't make traffic?

Sorry, "all the rest at A" :)

Post your HTB script and I (and probably others) will have a look at it.

This is  the script:
//
#!/bin/bash
STEFANO="00:0F:B0:5F:A6:AD"
NEWDEV="00:13:D4:20:3B:46"
VPN3="00:13:A1:60:3B:AA"
MARK_STEFANO=1
MARK_PAOLO=2
MARK_VPN4=3

tc qdisc del dev eth1 root

iptables -t mange -F
iptables -t mangle -A PREROUTING -i eth0 -m mac -mac-source $STEFANO -j MARK -set-mark $MARK_STEFANO
iptables -t mangle -A PREROUTING -i eth0 -m mac -mac-source $PAOLO -j MARK -set-mark $MARK_PAOLO
iptables -t mangle -A PREROUTING -i eth0 -m mac -mac-source $VPN4 -j MARK -set-mark $MARK_VPN4

tc qdisc add dev eth1 root handle 11: htb
tc class add dev eth1 parent 11:0 classid 11:1 htb rate 100Mbit ceil 100Mbit burst 6k cburst 64k quantum 1600
tc class add dev eth1 parent 11:1 classid 11:2 htb rate 70Mbit ceil 70Mbit burst 6k cburst 64k quantum 1600
tc class add dev eth1 parent 11:1 classid 11:3 htb rate 20Mbit ceil 20Mbit burst 6k cburst 64k quantum 1600
tc class add dev eth1 parent 11:1 classid 11:4 htb rate 10Mbit ceil 10Mbit burst 6k cburst 64k quantum 1600

tc qdisc add dev eth1 parent 11:2 handle 20: sfq preturb 10
tc qdisc add dev eth1 parent 11:3 handle 20: sfq preturb 10
tc qdisc add dev eth1 parent 11:4 handle 20: sfq preturb 10

tc filter add dev eth1 protocol ip handle $MARK_STEFANO fw flowid 11:2
tc filter add dev eth1 protocol ip handle $MARK_PAOLO fw flowid 11:3
tc filter add dev eth1 protocol ip handle $MARK_VPN4 fw flowid 11:2
\\

We have tested this script with CEIL=RATE, and CEIL=100Mbit, but i view that the data-rate calculated for each PC is not proportional to the traffic assigned at Firewall.

Many thanks.
