I have a G5 Mac, I have set up the airport express linked to my existing wireless network. Streaming of music to my amp works fine.

But now I would like to connect my blu ray player which has a eternet port on it but doesnt have wireless capabilities.

How do I set up the airport express so I can use the ethernet port on it to connect my blu-ray player to the internet for updates etc.?

I have tried different settings but with no success

My existing wireless network is through a Netgear DG834GT

Thanks in advance
