Oh so helpful! In the howto it only mentions how to do this on a single port basis - and I cant find TC documentation: # tc filter add dev eth0 protocol ip parent 10: prio 1 u32 match ip sport 80 0xffff flowid 10:1 I assume after the 80 we have a hex mask, so would the following match ports 10240->10751? # tc filter add dev eth0 protocol ip parent 10: prio 1 u32 match ip sport 10240 0x200 flowid 10:1 Thanks in advance, Mark At 11:04 11/02/2002 +0100, Stef Coene wrote: >On Sunday 10 February 2002 23:25, Mark beck wrote: > > Hi, > > > > I want to POLICE to a certain bw in one direction only - over a range of > > 500 ports.
