I am looking for a way to control the rate of data on a specific Ethernet port on my WRT54G-TM.

I have the options in QoS, but unfortuantely see these don't work on the broadcom chipset.

Does anyone have any suggestions how I might slow the rate down.

I need to in order to test some older equipment that even 10M seems to be running a little fast for.

Any help would be gratefully recieved.

TIA

I see the special version allows per user bandwidth management.

Does it work on a WRT54G-TM though?

I'm not sure if this is working completely correctly, but it does seem pretty good.

Code:
tc qdisc del dev br0 root
tc qdisc add dev br0 root handle 1: cbq avpkt 1000 bandwidth 10mbit
tc class add dev br0 parent 1: classid 1:1 cbq rate 2900kbit \allot 1500 prio 5 bounded isolated
tc filter add dev br0 parent 1: protocol ip prio 16 u32 \match ip dst 192.168.1.2 flowid 1:1


I'm sure the script could do with some tweaking, but by altering the 2900kbits up and down a bit the rate is altering with it, so looks good.
