So, I can video-chat to Simon Phipps in his place in Southampton, England just fine. Steve Gillmor can video-chat to Simon too. But Steve and I can’t video-chat to each other. ConnectionDoctor says Steve’s not responding to my UDP packets. NatCheck says nothing’s wrong. I turned off my firewall, but I’m sitting behind a DSL modem and a D-Link router that may be screwing things up. Mark me puzzled. [Update: Flip Russell, who’s been around this track, writes to tell me that here and there around the Internet are routers that just don’t route UDP, and that if one of those is between you and whoever you’re trying to iChat with, audio/video just isn’t going to happen, and there’s probably nothing you can do about it.]
