Controling Inbound and Outbound traffic simultaneusly.

[Diego Cabrero]

Hi,

I'm Running two independent traffic applications between two computers 
conected point to point each other, at the same time each of these 
applications are generating trafficin one direction so i have two 
independent traffics traveling througth the same channel.

Figure:
                eth1, PC1 ---------app1-----------> eth1, PC2
                                <--------app2------------

My problem is that i am trying to control the whole inbound and outbound 
traffic through PC1 (by using IMQ for ingress) but it seems like they 
are connected somehow.

This is the script i am using:
---------------------------
Inbound control commands:
            tc qdisc add dev imq0 root handle 1: htb
            tc class add dev imq0 parent 1: classid 1:1 htb rate 
${INBOUND}kbps ceil  ${INBOUND}kbps
            iptables -t mangle -A PREROUTING -i eth1 -j MARK --set-mark 1
            tc filter add dev imq0 protocol ip parent 1:0 handle 1 fw 
flowid 1:1
            iptables -t mangle -A PREROUTING -i eth1 -j IMQ --todev 0

Outbound control commands:
            tc qdisc add dev eth1 root handle 2: htb
            tc class add dev eth1 parent 2: classid 2:1 htb rate 
${OUTBOUND}kbps ceil  ${OUTBOUND}kbps
            tc filter add dev eth1 protocol ip parent 2:0 prio 3 u32 
match ip dst 0.0.0.0/0 flowid 2:1

Any ideas?

Thanks!!
