LARTC - Sep 2003 - Anyone with a similar setup want to share their setup?

Hi!

We currently have T1 to provider A, T1 for peering only to provider B, and
10M Ethernet to provider C. A and B bill is a fixed rate, C bills us based
on usage.

We have 4 interfaces on our router, one facing each provider, and the last
facing ourselves.

I''d like to rate-limit provider C to a given amount - I can do that
outbound
easily enough, how about inbound - anyone got a sample?

I could throw in a second machine doing bridging and rate limiting, but that
doesn''t seem like much fun.

Take a look at the IMQ + HTB doco.

or, throttle the incoming traffic the easier (and less efficient) way with the 
ingress policer.

If C is feeding _through_ your router to your LAN, you can rate limit
_egress_ to your internal network from C. It''s a bit of a hack doing it
that way, but it works well enough from experience. If your router is
the consumer of traffic (ie a proxy server, or such) then probably you
want to play with ingress policing.
