Hi guys,

My linux box has 3 network adapter. eth0 connects with ISP, eth1 is for staff network, eth2 is for public user. I want to limit the usage of internet bandwidth. for example, the traffic going through eth0, 75% is for staff network, 25% is for public user.

In addition, I setup shorewall on it for port forwarding and filtering, but I felt the traffic shaping of shorewall is complex. I don't need the specific TOS, but only the percentage. could you give me some suggestion?

Which software or package I should use to achieve this goal?

Thanks.

There may be a better way to do this, but have you had a look at squid yet?

You can set 'pools' and have certain bandwidth per pool.

You need to specify each network range (in the case the staff and public user networks are on different subnets) via ACLs and then specify what pool they are in.

From there you can specify how much bandwidth to allow for the overall pool and then each individual IP address.

Using this, you can specify a maximum bandwidth per pool.

Might change the shorewall to untangle on a VM and run everything through the untangle or just make the entire box untangle.

This might help.
