HEllo all- We are interested in limiting the bandwidth of a newly setup connection. We are on a 100 Mb/s switch port and want to keep it to 1 Mb/s for now. Forgive my ignorance, but do they measure this cumulative(inbound + outbound)?....I would assume so, but I would like to confirm this since the rate for overage is not within the budget for now. Assuming the conservative, how does the dummynet config have to be setup fpor thsi to occur?...or can it be configured for both inbound and outbound? Right now, I have the below config and since I have not put the box on the network yet, I have not been able to look at the MRTG to figure the answer. I am thinking that this config may limit to 1 meg in both directions....I am just not looking forward to overage fees right off the bat! btw, this config is for the priority of the udp/tcp acks in both directions. I am not sure if this is going to work so any comments on it would be appreciated. thanks, Bob ipfw -f flush ipfw pipe 1 config bw 1000kbits/s ipfw queue 1 config pipe 1 weight 100 ipfw queue 2 config pipe 1 weight 1 mask all ipfw queue 3 config pipe 1 weight 100 ipfw queue 4 config pipe 1 weight 1 mask all ipfw add 100 queue 1 udp from any to any out via fxp0 ipfw add 101 skipto 1000 udp from any to any out via fxp0 ipfw add 100 queue 3 udp from any to any in via fxp0 ipfw add 101 skipto 1000 udp from any to any in via fxp0 ipfw add 110 queue 1 tcp from any to any out via fxp0 tcpflags ack ipfw add 111 skipto 1000 tcp from any to any out via fxp0 tcpflags ack ipfw add 110 queue 3 tcp from any to any in via fxp0 tcpflags ack ipfw add 111 skipto 1000 tcp from any to in out via fxp0 tcpflags ack ipfw add queue 2 ip from any to any out via fxp0 ipfw add queue 4 ip from any to any out via fxp0 ipfw add 1000 allow all from any to any
