Can someone clarify QoS for me? I get the basic 'prioritization' idea behind it, but I'm confused as to how it's implemented in the network. If you have a modem, a router and a switch, do all three devices need to support it? Does anything need to be configured at the client PCs? Does QoS have some default actions with manual prioritization options to complement it, or does it not do anything unless you specify everything manually?

Oubadah:
Privoxy: IP address, MAC address, subnet, or adapter.


Pardon my ignorance, but by adapter do you mean it can?differentiate clients by their actual NIC hardware (making it impossible to bypass like one could by spoofing a MAC)?


Yip.

In the case of QoS for pfsense, TomatoUSB, DD-WRT etc it's basically rate shaping and prioritisation done at the router (tomato, dd-wrt) or machine (pfsense).

You indicate in the admin ui your approximate download and upload rates then specify what applications/ports/protocols will have priority and what percentage of the available up/down bandwidth they should be allowed when the line is saturated.

Without any QoS one person downloading a torrent can hog or saturate your upload and download bandwidth leading to everyone experiencing significant latency on gaming, voip, web browsing etc.

All this is made very easy on PFsense - It includes a wizard which you follow along and a couple of boxes and you are done (For basic QoS anyway).
