Stef,

Am I overlooking something obvious?

I'd suggest that Tomas throttles his bandwidth on transmit to the internal
network.  It is a router, so very little traffic will be initiated from
the router itself.

Why not perform traffic control on packets transmitted to the Internet on
the outward facing NIC.

Then perform traffic control on packets received from the Internet on the
inward facing NIC.

What's wrong with this?

 : You can give the download 98% of the link so there is always 2% available for
 : something else.  It also helps to throttle down _all_ incoming bandwidth to
 : 99% of your link so _you_ are shaping and not your router.
