Motorola SGB900 and PS3 media server problems

Hello,

Recently I installed MediaLink, ps3 media server and eyeconnect on my mac mini. My PS3 does not find a media server of any type and displays upnp as "not available". I did do some research and could not find a solution.

My router/access point is a Motorola SGB900. In the router admin, there is not an option for Upnp.

What do I need to do in order for any/all of these media servers to work on this setup?

Thank you.
