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 > > On Fri, 21 Dec 2001, Yusuf Goolamabbas wrote: > > > Hi, I've reported some kernel panics on freebsd-net,freebsd-stable which > > occur when dummynet/bridging is used on 4.4-stable. > > > > Would it be possible for the qa team to construct a simple traffic > > shaping bridge and and verify if there are no regressions > > Hmm.
