This is a general networking -- not just wireless -- query, but what the heck, y'all are pretty knowledgable. I've googled around and like that, but I can't seem to figure out:
I don't live in the USA. I have a Netflix account in my own country, but the stuff available is crap compared to the real USA-based Netflix. I subscribe to a very good commercial VPN service. If I want to watch the US version of Netflix on a computer screen, I can log in to one of my VPN's US-based servers and bingo, I get the full US Netflix in Firefox (e.g.). I run squid (proxy server) on Arch Linux on an old core 2 duo laptop, and if I set Firefox on my older MacBook Pro (core 2 duo) to use the Linux laptop as proxy connected to my VPN -- bingo again: US version of Netflix.
I can hook said MacBook Pro up via VGA to my 50" teevee and get US Netflix on the big screen, and it's pretty cool. We also have a 27" iMac that does a pretty tasty Netflix.
Ah, okay but: I have a networked Sony BD player, with a Netflix button. I set up the BD's networking to use my proxy server, but I can't get the US Netflix because the set-top-box seems to know where I am via DNS or something. What do I need to set up on my Linux laptop to fool the Sony? I know that there are "smart DNS" services available, but I have no idea how they work.
