Default PF/ALTQ rules not working as intended

I am attempting to limit all clients on the network to 128Kbps down and 64Kbps up. This is *sort of* working, except that for some reason, ALL clients are falling under the "c1" queue (which is the default), instead of using the ones written specifically for them.

Here is my pf.conf:
Code:
$ cat /etc/pf.conf
int_if="rl0"
ext_if="nfe0"
int_net="192.168.2.0/24"

principal="192.168.2.2"
c1="192.168.2.3"
c2="192.168.2.4"
c3="192.168.2.5"
c4="192.168.2.6"
c5="192.168.2.7"
c6="192.168.2.8"
c7="192.168.2.9"
c8="192.168.2.10"
c9="192.168.2.11"


altq on $int_if cbq bandwidth 3Mb queue { principal_d,c1_d,c2_d,c3_d,c4_d,c5_d,c6_d,c7_d,c8_d,c9_d }
altq on $ext_if cbq bandwidth 1Mb queue { principal_u,c1_u,c2_u,c3_u,c4_u,c5_u,c6_u,c7_u,c8_u,c9_u }

Well, clearly and unfortunately this thread never got a reply and I was forced to switch to ipfw/dummynet for the bandwidth limiting. I'd rather be using pf for its advanced packet shaping features, but sometimes we have to settle for what gets the most important part done.

I don't have means to simulate and try your config right now as I am on a Windows machine, but you could've tried to generate traffic and then run pfctl -vv -ss (and possibly pfctl -vv -sr) to see which rule(s) put traffic into default queue so you can investigate why.
I see you got the problem solved but It's worth knowing why it didn't work.

Can you do an ascii-art network diagram (topology). I think the reason your rules aren't hitting are --perhaps-- because you have the inside-outside ip addresses and the to-from mis-aligned.

Code:
pfctl -vvsrules
will show you the rule "hit" counts. I suspect they'll be zero.

Ok.
