I have been talking to Luigi and sent him my config.
Basically, I have a simple bridge. fxp0 connects to a switch port and
fxp1 connects to another switch (switch 2) on which I have various
servers. The objective is to traffic shape each server on switch 2 to
have max 512 kb/s outbound bandwidth excluding traffic being sent to my
ofice IP space
The rules follow, $range and $office are edited out
${fwcmd} add 100 pass all from any to any via lo0
${fwcmd} add 200 deny all from any to 127.0.0.0/8
${fwcmd} add 300 deny ip from 127.0.0.0/8 to any
# If you're using 'options BRIDGE', uncomment the following line to pass
ARP
${fwcmd} add 400 pass udp from 0.0.0.0 2054 to 0.0.0.0
${fwcmd} add 500 pass all from ${range} to any in via fxp0
${fwcmd} add 800 pipe 1 ip from ${range} to not ${office} in via
fxp1
${fwcmd} pipe 1 config mask src-ip 0x000000ff bw 512Kbit/s queue 50
