[ubuntu] Use ubuntuserver as router?

view story

http://ubuntuforums.org – Hi everyone, I have bought a apple tv 2 which I world like to stream content to from my ubuntu server (10.04). I have set it up wireless through my router but soon realised that I will nerver get the throughput that I need to make it work. Now the apple tv and the server are not that far way from each other so my idea was to connect the apple tv to the ubuntu server via ethernet so that when streaming content from my server it will be smart enough to just take the content directly from the server without going through the router and if I access the internet from my apple tv 2 then it goe (Hardware)
