I can not run ichat av when I am connected to the internet via wireless (Zyair B-2000). When I am directly connected via ethernet everything goes well... Do you have experience with Zyair B-2000? It is not included in this "compatiblle"-list from apple... Thanks for replay. Ziranda Hi,

I have problems with my iChat av/audio. I can not run ichat av when I am connected to the internet via wireless (Zyair B-2000). When I am directly connected via ethernet everything goes well…

Do you have experience with Zyair B-2000? It is not included in this “compatiblle”-list from apple…

Thanks for replay.

That's using a proxy server to do the initial handshaking and then tricking the routers into opening up the ports. It's <a href="http://www.ietf.org/rfc/rfc3022.txt">RFC 3022</a> for the interested. But then why would Apple say iChat AV is only compatible with that very specific list of routers? Most of those routers seem to support UPnP. Interesting.

But I could be wrong. It is actually fairly easy to tunnel through two well behaving NAT routers in this fashion. Particularly UDP. This is a common technique used in a lot of networked games. See http://midcom-p2p.sourceforge.net/ for more information. I’d be suprized if Apple’s Airport supported UPnP. But I could be wrong.
