Hi,

I have QoS working where I limit each user to 512kbps/512kbps. But I want to limit the total bandwidth used by the DD-WRT router to 3Mbps total. My pipe is 10Mbps/10Mbps but I can't have the public wifi taking it all up.

How do I max users out at 512kbps/512kbps and total WAN bandwidth to 3Mbps/3Mbps?

I have a WRT54GL v1.

Thanks!!

Limit the number of IP addresses in the DHCP server (default is 50). For example: max 10 IP adresses, at 0,3 Mbps each = there will never be more bandwidth used than 3 Mbps.

Tip: decrease the DHCP lease time to 10 minutes (default is 1440 minutes), which causes each connected client to automatically renew every 5 minutes. So your 10 IP addresses will be used optimally.

I myself am using QoS on a Linksys WRT54GL v1.1, Special edition build 15962. I have noticed that increasing the amount of IP adresses above 10, causes bandwidth instability (not connection instability, but purely the bandwidth). So 10 should work fine for you as well, I suppose.

Interesting way of doing this. I might try that. Hoping there is some kind of iptables/tc command that would easily limit the WAN port to a certain limit.

I'm contacting my ISP to see if they can limit the bandwidth by IP address on their end (using metro ethernet). This would be the best solution.

Thanks.
