Help setting up bridge interface


Ok so I have a raspberry pi downstairs connecting via wifi. I also have a blu-ray player that loves to eat all my bandwidth when streaming Netflix connected via wifi.

My goal is to bridge the physical port of my raspberry pi with the wireless adapter so I can connect my blu-ray player to it via a wire and connect to the internet that way. This should allow me to limit the available bandwidth to the blu-ray player using something like wondershaper.

I would use the routers QoS but it is ISP supplied and they won't give me the username/password to change any settings.

I am trying to follow this guide. I have all the software installed (ebtables and bridge-utils). I am able to create a bridge manually but as soon as I plug my blu-ray into the pi, the connection dies. Most likely due to the issues mentioned in the article. Also when running
ifup br0
it says it can't find that interface, which I don't think is right.

My pi uses a static IP specified in the interfaces file, I would like the blu-ray player to be DHCP as I don't care what IP it pulls. Or static if it makes this easier, I really don't care.
Here is a look at my interfaces file and my listed interfaces. As you can see br0 isn't showing up when setting it up via interfaces, it does show up if I do it manually like in the guide. As far as I can tell doing it via interfaces is mandatory if my router drops the connection when I plug in my bridged device.
Can anyone provide assistance in getting this bridged connection up? I manage a few linux servers on a daily basis so I'm pretty proficient in most areas but networking is one that I always manage to have issues with.

I appreciate any help.

What you're trying to achieve isn't "bridging", that's generally making two connections usable to the O/S as though it was one.

What you're trying to achieve is to use your Pi as a router.

So it should be a matter of doing IP forwarding with NAT from the ethernet interface through the Pi wifi interface.
