Hi Simon, thanks for your quick response!

If you are running MinimWatch on a Windows computer, try completely disabling the Windows firewall to see if this fixes the problem. If it does, you need to configure the Windows firewall to allow Java to accept incoming connections.

Didn't help.

Minimwatch on Win7 64bit, Minimserver on a Synology DS115 (Installation from official package).
Two network adapters as shown in the picture.
