Here is a firewall script I put together that will limit download bandwidth based on 1 or more ip addresses. Obviously you need change the CLIENT_IP to the IP you want to limit. Copy and paste it into Administration --> Scripts --> Firewall. After saving it, reboot router for the script to take effect. Thought someone might find it useful. Code: DEV="br0" CLIENT_IP="192.168.1.104 192.168.1.111" LIMIT_DOWN=30 tc qdisc del dev $DEV root 2> /dev/null > /dev/null tc qdisc add dev $DEV root handle 77: htb tc class add dev $DEV parent 77: classid 77:1 htb rate ${LIMIT_DOWN}kbps tc filter add dev $DEV parent 77: protocol ip handle 80 fw flowid 77:1 for ip in $CLIENT_IP; do iptables -t mangle -I POSTROUTING -d $ip -j MARK --set-mark 80 done
Intriguing. I'm almost considering this. Just to ask first though: The limit I'm guessing is modifiable. But which one? Limit_Down (And if so, how is it determined?) or htb rate 20000kbit?
zapoqx, I've modified the script quite a bit. Removed some stuff that wasn't really necessary. Although officially kbps is an abbreviation for kilobit per second, htb qdisc uses it as kilobytes per second. Anyways, think of data rates as kilobytes per second when using this script. So the script I posted above is limiting two ip addresses to 30 kilobytes per second downloading capability. let me know if you run into any issues.
