Hi list
I have a jail with 4 ips, say 10.10.1.1-4, the net interface is lnc0.
I would like to use ipfw(8) and dummynet to control the bandwidth of the
jail, also the different ips. I know that only limit the jail's inbound and
outbound bandwidth is very simple. But for the multi-ip jail, I guess that
I should use the dynamic queue rules of ipfw(8).
My idea is like this: configure the jail's pipe for given bandwidth,
while the 4 ips with 4 queues with different weights. The jail's pipe is
the 4 queues' parent pipe. They share the pipe's bandwidth. The 4
queues can be created using the "mask" option in ipfw(8) rule. Is this
feasible?
I've read the ipfw(8) man page, but found ALMOST nothing about the
jail related configuration. I also googled the Internet, few things helpful. I
am not very familiar with ipfw and dummynet. Any one with any hints or
directions is appreciated!
Thanks!
Jas
