Bandwidth Throttling
 

Hi,

I have a computer installed with openBSD and i am using it as my gateway/firewall. My question is how can i do bandwidth throttling (or capping)? I want to limit the speed that is downloaded from my servers behind the firewall?

Is this possible with BSD, if so what do i use to do it?

Also is it possible to just throttle a specific port number?

Thanks

You can use Squid Proxy server.... it has a feature called "delay pools"

Check this:

You might want to look at altq. In 3.3, it's built into pf.

Squid will help you control traffic through protocols it supports. For true bandwidth throttling or other traffic shaping use the QoS features in altq like stickman suggested. This way you can control the matter on your firewall, which is the logical location to do this anyway since your connection likely terminates there or nearby.

The PF user's guide will teach you all you need to know about using altq integrated with pf to do this.:
