Thanks for your patience and answers! Your second answer nailed it. No more firewall blocking log messages. 3478 UDP + TCP are the only ports I was missing.\r\nInterestingly the connections are lost despite that.\r\n\r\nWhen I'm using palava.tv everything is rock solid (tested yesterday pair programming for > 1 hour), several machines, browsers, even arm + i86. Rock solid.\r\n\r\nWhen I'm using my own installation losing connection after 1-2 min. \r\nThe installation is publicly available at http://www.informatom.com/webpages/videochat (no password whatsover) and I based it off the minimal [example](https://gist.github.com/thammi/9005857).\r\n\r\nJust one warning in the Javascript console ('webkitURL' is deprecated. Please use 'URL' instead.) But that warning is also there with palava.tv as well.\r\n\r\nAlso, when I use palava.tv and connect 10mins later, they find each other like a charm, within under 1s. In my own install, I have to connect within seconds, otherwise no connection. I must be doing something fundamentally wrong...\r\n\r\nGoing to give it another debugging retry tonight...."}}
