Hi everyone,

I am wondering, what is the best way to do some 'generic shaping' on a 
firewall/gateway box.
Currently, I'm just running a wondershaper variant on the WAN interface.
htb qdiscs for outbound, and ingress policer for inbound.

Now, assuming most traffic (except DNS requests etc) goes through the firewall, I 
could shape on the LAN side as well.

Should I put htb qdiscs on WAN as well as LAN and not use any ingress policers ?
or should I use them as well?

also,
with rules like this:
tc qdisc add dev ppp0 root handle 1: htb default 20
tc class add dev ppp0 parent 1:1 classid 1:1 htb rate 512kbit burst 6k
tc class add dev ppp0 parent 1:1 classid 1:10 htb rate 512kbit burst 6k prio 1
tc class add dev ppp0 parent 1:1 classid 1:20 htb rate 460kbit burst 6k prio 2
tc class add dev ppp0 parent 1:1 classid 1:30 htb rate 409kbit burst 6k prio 2

Will the slower queues be able to borrow extra bandwidth from the faster ones (when 
they're not in use), or do I need to specify the ceiling parameter to allow that?
I'm a bit unsure of the default behaviour of the htb qdisc.

thanks
