I can not open bugs, yet, so I post it here, nothing big:
System -> Server -> Edit Server IP
Selecting "Server" (VM Applinace), does not show an IP. If entering one in the field on the right an hitting enter, I end up at the add user page.
Another thing, I guess the DNS-Server is active when running the VM Applinace? I ran it in bridged mode, changed the IP in the interface list, and the config in the webinterface. But digging a testdomain + a record, added in the DNS ends up in "query refused"...
