So, PF + ALTQ does not allow for incoming bandwidth limitation?
For bandwidth, ALTQ already provides that. It should be pretty easy to
implement a discipline to do that for packet rates as well. Note that it
only applies to out-going (and indirectly for forwarded) traffic.
It can technically, but you can't force the other end of the line to
control packet output according to rules on your end. What works is
limiting recieve/forward buffers so your host sends e.g. source quench
messages earlier, but you can never be sure the host on the other end
cooperates. Especially not in any complicated priority scheme. The same
thing applies for any other solution for bandwidth limiting, be it
dummynet, wondershaper, altq or whatever.
