I also have problems like Mr. Waldir.
To solve this, it can be classified as ports and limiting bandwidth per port,like you says.
Only, I think so, is there any kind of additional program or patch, so that bandwidth managers can recognize the ip client though traffic is passed through a proxy server?
I have read about TProxy , which are able to make squid to be bridged, so that clients ip can be recognize by the bandwidth manager (not NAT)
Is it possible, be installed directly into the ClearOS squid, because to do the installation TProxy must perform kernel patching and squid patching itself.
Just about the idea .. Who knew It could solve this problem.
Or from the developer there another solution? improvements, perhaps? for the next version?
