[altq 1203] Re: traffic shaping (fwd)

[Denys Sene dos Santos <sene@cptec.inpe.br>]

	I have the same problem. I need to limit incoming traffic.
	if I have something like a Squid in this router, and
I don't want that it uses all my bandwidth to download the pages
for the clients behind the router (with a nat).
	This is a typical scenario for me, when a sell a link
of 64Kbps, 128Kbps or any other, through wavelan links of 11Mbps
and I want that the client router only uses its bandwidth, to
squid download the pages, or to receive the e-mails, etc.
