The wondershaper indeed is a very nice script, but I think that it doesn't exactly fit your needs. It's made to optimize your internet connection by minimizing the delay of interactive traffic and removing long queues, which improves latency. However, I think that it is a good starting point to see how a TC script is set up. For a solution to your problem see for example: http://lartc.org/howto/lartc.ratelimit.single.html It's based on the CBQ classfull queueing discipline. I have no experience with the CBQ qdisc, but am using the HTB (as is the new version of the wondershaper), which is recommended in most documentation. You probably need two things in your TC script: a classfull qdisc (e.g. HTB) and filters that place traffic from specific IP's into the different classes of that HTB qdisc. It would look something like this (no guarantees that it works): tc qdisc add dev $DEV root handle 1: htb default 10 tc class add dev $DEV parent 1:1 classid 1:10 htb ${CONNRATE}Kbit prio 1 tc class add dev $DEV parent 1:1 classid 1:11 htb rate ${RATE}Kbit prio 2 tc filter add dev $DEV parent 1: protocol ip prio 18 u32 match ip src $IP/$MASK flowid 1:11 Where $DEV is the ethernet device of your outgoing connection, $CONNRATE your upload speed, $RATE the limit upload speed of the computers with IP $IP and netmask bits $MASK (for one IP, set MASK 32). Rate limiting incoming traffic is a lot more difficult, because you can only drop it to slow it down. Hope this helps you get started.
