The new AEBS, UPnP and Xbox 360/PS3

Nope, UPnP is an Microsoft technology. Apple has it's own NAT-PMP plus Bonjour.

If you know which ports to open, you can do it manually through the Airport Utility.

If you want to stream music or video from iTunes to TV, you would use the Apple TV.

If you must have UPnP, then the Apple stuffs are not for you.

We currently use ABES as our household router. We have 2 xbox 360s and a PS3 connected, the Xboxes ethernet and the PS3 wireless. Our NAT shows as Open on the Xbox Connection test. Our settings are on default for the ethernet. So at least for your gaming, there shouldn't be any issues.

As for the streaming, I don't know.

I use an application called "Connect360" on my iMac which makes the media content on it available as a UPNP AV media server to my XBox360. Works fine using an AEBS. NB: There are other similar apps available to make content available to UPNP media players from OS X but the only one I can remember the name of right now is Connect360 because I have it running on the machine I am typing this on 🙂

BTW don't let the similarity of the names "UPNP" (ie automated port opening/mapping between your private network and the external internet, which NAT-PMP is similar to) with "UPNP AV" (which is more-or-less standardised discovery and streaming of media content within your local network only and pretty-much only needs non-broken multicast support to work correctly) confuse you; it is entirely possible for a given router or computer to work 100% with one of these and 0% with the other.

FWIW, my sons' XBox 360 Elite runs fine on our Gigabit AirPort Extreme 802.11n (5 GHz) based network. Nothing special, but I did reserve a specific IP address for the XBox.

And as for content streaming, take a look at EyeConnect from El Gato:

It allows you to stream from your Mac to your UPnP devices.

I think you mean DLNA. That's the media server technology that both the Xbox360 and PS3 use. UPnP is a network protocol that has nothing to do with serving files.

Check out NullRiver... they make Connect360 and PS3 MediaLink -- they both allow your game system to see your Mac as a media server. It also allows iLife sharing of (non-protected) music and photos. I compress HD Quicktime movies with Quicktime Player Pro's AppleTV preset and they play on my PS3 perfectly.

I just received my new AEBS Dual Band today. The Guest Access to the internet is pretty nice.

On my PS3, it reports NAT Type 2, but no UPnP. Using new Xbox Live Experience UI, I didn't get any errors when I tested my XBL connection. So it all works fine.

No I mean UPNP.

DLNA is built on top of the UPnP specs, and DLNA also includes other pieces as well, like jpeg, mpeg, http....

DLNA uses the UPnP to discover network devices and setup port mapping.

If Apple joins the DLNA tomorrow, there is no reason why Bonjour+NAT/PMP can 't be added to the UPnP layer, and making DLNA work with Apple products.

Good suggestion about "Connect360", it shows UPnP can NAT/PMP can coexist.

Are you able to connect wirelessly from the xbox 360 to the guest network with encryption turned on? I'm having difficulties connecting to the new dual band AEBS with my xbox...

Sorry, my Xbox is wired to the AEBS. My PS3 connects wireless without any problems using WPA2.

Short answer, you don't need UPnP to stream to your ps3 and 360, I use medialink to stream from my mac to my PS3 works awesome, I imagine Connect360 works just as well as it's the same company (nullriver).
hope that helps
