Bandwidth limiting of outgoing traffic

Hi all!

Has anyone been able to accurately shape the bandwidth consumption of freenet traffic leaving your server? I know there are options in freenet.conf, but it seems that these are either ignored totally or at the very least not very strictly abided by…

Since Freenet uses random ports for outgoing traffic, I can’t really shape it on my firewall either. (I do have an option to shape traffic based on packet content. Do all Freenet packages have some common, unique content perhaps?)

The Freenet site suggested to control the bandwidth usage on the OS-level instead. Who can tell me how to do this?
