Hi All

I'm trying to get TC working to limit inbound and outbound traffic on interfaces. Inbound works perfectly, but outbound seems to run at full speed regardless of the settings I use.

Example:
tc qdisc add dev <interface> root handle 1: htb default 10
tc class add dev <interface> parent 1: classid 1:10 htb rate 10mbit

The above works perfectly to limit inbound traffic to 10mbit, but outbound still runs on full. All the documentation out there seems to be based on IP or port, we need it per interface

If anyone can point me in the right direction it would be really appreciated

Thanks!

Actually, unless you control both end points, due to how TCP/IP works, it doesn't. Basically if you're the server side then you can influence the remote end point transmission rate by slowing down your responses but you can't force them. At least that's how I understand it, consult the LARTC if unsure.


No, you can actually do something like '/sbin/iptables -t mangle -A POSTROUTING -m mark --mark 0x0 -j MARK --set-mark [whatevermark];'
