    Sort of. It works, but I think that a computer "leases" a UPnP session
    for some time. It may just be my router, but I think I had to restart
    the machine I was talking on before I could talk on another machine. I'm
    not sure if this is 100% true from playing around. If you can get a
    UPnP-enabled router, play it around and see what you come up with. :)
    See below for more on UPnP.

    Yep, other routers as well. I can't speak for AirPort, but it should
    work with any router that supports NAT traversal w/ UPnP to my knowledge.

    I sent a report into MacinTouch that iChat AV uses UPnP after doing a
    little bit of packet sniffing. I have a D-Link DI-704P (revision B with
    a titanium case rather than an older brown case) and I did not have to
    do any configuration changes with the router to talk. Packet sniffing
    shows a request going to 192.168.0.1 (my router) that requests port 5060
    to be mapped, and mentions UPnP. I don't use video chat - that's why the
    other ports aren't mapped.

    You basically need to ask your router manufacturer and make sure you
    have the firmware revision that enables it. For example, my DI-704P
    didn't support it until the very latest official revision from D-Link's
    site, version 2.70. I'm using revision 2.72a from their Taiwan site,
    because it fixes many annoying bugs in 2.70. Haven't tried 2.73 yet
    because this revision's working fine for me. Anyone interested, the
    Taiwan site is:

    [url]http://tsd.dlink.com.tw/downloads.htm[/url]

    It's under Internet Gateways. If anyone needs someone to test iChat AV
    out with, my AIM name is doogul.

    I just downloaded the new version of iChat from Apple. I have a one
    gig G4 computer with a firewire camera and a cable modem connection to
    the net that runs at about the speed of a T3 phone connection. Would
    this configuration work with the new iChat? It would be very
    interesting to try this out. Is there some place I might be able to
    find people interested in testing connections?

    Thanks for any help or insight anyone might offer.
