Bridge + PF + ALTQ: Is this possible?

[freebsd-questions at premsoft.co.za]

Hello all,

Is it possible to have FreeBSD configured as a bridge and let PF do
filtering of the traffic and ALTQ do shaping of the traffic?

My common sense tells me that this should be possible, as it is possible
using  IPFW/IPFilter and DUMMYNET.

If it is possible, are there any pitfalls that I must watch out for?

I will be using FreeBSD 6-STABLE.

Thank you in advance.
