He Ali, thank you for your reply. As I said I didn't change any lines but those I listed in my description. The basis was the server.config found in the following archieve:
https://dist.apache.org/repos/dist/dev/incubator/wave/0.5-incubating/apache-wave-bin-0.5-incubating.zip Also you answer made me try the rc4 release version again, and you were right it got to have something to do with the new rc5 version, because I got the rc4 working again, even over internet, basically with the same config settings I used for the rc5. Best regards, Ronny
