 classid 1:1
   $TC filter add dev $DEV parent 1:0 protocol ip prio 2 handle 5 fw classid 1:2

Yes, this script work. I compared with my script and i observed that i 
get the error message only when i have the same prio for the filters. 
Try the fw filter with prio 1 handle 5 fw

Different prio's will solve my problem but still i'm curious

  $TC qdisc del dev $DEV root

  $TC class add dev $DEV parent 1:0 classid 1:2 htb rate 4096kbit

  $TC filter add dev $DEV parent 1:0 protocol ip prio 1 u32 match ip dst $LAN classid 
1:1
  $TC filter add dev $DEV parent 1:0 protocol ip prio 2 handle 5 fw classid 1:2

 Using either u32 alone or fw alone work, so can't be a kernel or tc 
 problem (2.4.21-ac1, tc with htb patch). 

Here: linux-2.4.21, tc binary which is available within [1].

 Looks like isn't allowed to mix different classifiers under the same 
 qdisc , but i didn't find any reference to this in the man pages, or 
 in the howto. Can somebody confirm this behaviour and/or explain?

At least here it seems to function. Stupid question: Are you sure that 
your kernel supports the fw classifier?

Bye,
Steffen
