pf and dummynet

[Paul Webster]

You can mix ipfw and pf, but beware of the order they are loaded (The first one loaded is inside the second one loaded) – it may be better in fact to compile them both in the kernel.

You basically end up with: (pf)(ipfw)(system)(ipfw)(pf) – assuming pf was loaded first

Subject: pf and dummynet

I have a box I need to shape inbound and outbound traffic. It seems altq
can only shape outbound packets and not limit inbound ?  If thats the
case, what is the current state of mixing ipfw, dummynet and pf ?
Writing large complex firewall rules works better from a readability POV
(for us anyways) so I really prefer to use it. But I need to prevent zfs
replication eating up BW over some WAN links, and dummynet seems to
"just work"

For ipfw I have


00010 6640359 9959147882 pipe 1 tcp from 192.168.128.0/20 to any
01000 3486901  228480912 allow ip from any to any

and then checking my pf.conf rules, it seems to block and pass traffic
as expected. 

Is there anything I should explicitly check ?
