This is exactly what Im trying to do, without success.... I'm almost
giving up.
I made a little test script, follows:
tc qdisc add dev eth0 root handle 1: htb default 22
# The LAN class:
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 90mbit
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 89232kbit ceil 90mbit
# The internet class:
tc class add dev eth0 parent 1:0 classid 1:2 htb rate 768kbit
tc class add dev eth0 parent 1:2 classid 1:20 htb rate 384kbit ceil 768kbit
tc class add dev eth0 parent 1:2 classid 1:21 htb rate 256kbit ceil 768kbit
tc class add dev eth0 parent 1:2 classid 1:22 htb rate 128kbit ceil 768kbit
# filter for the LAN:
tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 10 fw
classid 1:10
#Filter for internet:
tc filter add dev eth0 protocol ip parent 1:0 prio 2 handle 11 fw
classid 1:20
tc filter add dev eth0 protocol ip parent 1:0 prio 3 handle 12 fw
classid 1:21
tc filter add dev eth0 protocol ip parent 1:0 prio 4 handle 13 fw
classid 1:22

No error messages, everything fine.

A configured Apache to listen on port 3128, to make tests, and in a
machine in my Lan I do:

As you can see, the download speed is 92KBps, the 768kbits in my script.
but why the class 1:10 who haves garanteedrate 89232kbit wasn't used ?
the fw mark is working, I see the traffic going correctly, but the
correct filter is not applyed??!
Maybe some of you can give me a hand, I'm sure that something is
misconfigured, but I can't figure out where. I'm new in htb, and I read
the LARTC how to, and search google for a solution, but in vain, this is
getting me crazy!! Help me!!
