Here's my setup: 1 Airport Extreme base station 2 Airport Express' I have two ReplayTV's that connects via the Express' as a bridge. They work fine and see each other and stream video. How do I set up port forwarding so that I can use internet video sharing (IVS)? I've done it on my old linksys but never on the Apple hardware. I need for port 57320 to forward to the Replay in order to download video from another user. I've made no advanced settings in the Airport Admin utility so they are all the defaults.
