One last question then on a point that isnt clear in my head. The traffic I want to limit is gatewayed ed0 <--> fxp0 Do the statements/setup below only apply to packets destined for that interface (to be gated or for it specifically), ignoring all other packets on that ethernet? (I think all adapters see all packets, but only accept, deal with those corresponding to their IP or to be routed no?) Just seems like I should be saying something line in fxp0 out ed0 to designate the packet path. (but then I could just be needin more coffee today) On Thu, 3 Feb 2000, Dan Nelson wrote: > In the last episode (Feb 03), Steve Hovey said: > > > ipfw pipe 1 config bw 100kbytes/sec > > > ipfw add 100 pipe 1 ip from any to any out via fxp0 > > > ipfw pipe 2 config bw 100kbytes/sec > > > ipfw add 101 pipe 2 ip from any to any in via fxp0 > > > > I did this - checked the man pages - and soon as I do it, at > > 512kbits, a ping out that port drops 80% of packets, and reports > > enourmous ping times on the packets that do get thru.
