Equal bandwidth sharing by all hosts using dummynet

[Thomas S. Crum - 1WISP, Inc.]

Do not use "all" of your available pipe as during peak times it would
increase latency.

# EVERYBODY "DOWN"
add queue 100 ip from any to 192.168.42.0/24
queue 100 config weight 1 pipe 100 mask dst-ip 0xffffffff
pipe 100 config bw 1950Kbit/s
#
# EVERYBODY "UP"
add queue 101 ip from 192.168.42.0/24 to any
queue 101 config weight 1 pipe 101 mask src-ip 0xffffffff
pipe 101 config bw 350Kbit/s

# THIS ALLOWS DHCP TO WORK
add queue 250 ip from any to any
queue 250 config weight 1 pipe 250 mask src-ip 0xffffffff
pipe 250 config bw 10Kbit/s

It sounds as though you are using a seperate box for shaping?  If so, this
configed box would go in between your router and switch as a bridge.

Best,

Tom
