I have tried Googling for which TCP and/or UDP ports netflix uses for its streaming video. I have found a few pieces of information, some people saying saying that it uses port 80 (HTTP) for streaming and port 443 (HTTPS) for authentication.
Does anyone have any more info. on this? Can anyone confirm/deny that this is true?
With my current ISP (Qwest) I seem to get better performance if I turn on QoS tagging on my router (Linksys WRT610N). I want to enable QoS for the ports that Netflix streaming uses.
