Actually I do traffic shaping at the border router but I was looking for a 
more sophisticated solution to restrict bandwidth for certain services at 
the host itself (e.g. to limit ftp servers' upload speed to the internet).

I'm currently thinking about the latter, to put it between the router and 
the firewall as a pure traffic shaping solution. Meanwhile I use the 
following values:

altq on $extIF cbq bandwidth 1000Mb queue { std, traf_ext }
queue std bandwidth 990Mb cbq(default borrow)
queue traf_ext bandwidth 10Mb { traf_ext_ftp, traf_ext_http }
queue traf_ext_ftp bandwidth 50% cbq(borrow)
queue traf_ext_http bandwidth 50% cbq(borrow)

Thanks to both of you, Helmut
