rdr with round-robin ports

[Matt Burke]

I have a pile of server daemons running on localhost which I want to
load-balance between. I'm using the following rule on 8.2-STABLE (28 June
2011) to try to load-balance between them:

rdr inet proto tcp from any to 127.0.0.1 port = 2000 \
  -> 127.0.0.1 port 3000:3099 round-robin

Unfortunately pf seems to only redirect to port 3000, sending all
connections there and none to any other port.

I've also tried specifying {localhost, localhost, localhost...} port
3000:3099 with no success.

Am I missing something, have I hit a bug, or is the rdr syntax in pf.conf
misleading in that multiple ports in a destination is only valid if the
source uses multiple ports?
