Hi,

What's wrong with :
%%%
# Upload
ipfw pipe 1 config 100KBits/s
ipfw queue 1 config pipe 1 weight 25 mask src-ip 0xfffffff
# Download
ipfw pipe 2 config 100KBits/s
ipfw queue 2 config pipe 2 weight 25 mask dst-ip 0xfffffff
ipfw add queue 1 any from any to any xmit lnc0
ipfw add queue 2 any from any to any recv lnc0
%%%
Note that I didn't tested, this comes from my memory.
