[Users] OpenSer loops

Hello, my Openser is looping whenever an external call comes in. Internal calls from the same domain (route 1) are ok. Also from internal to external domains. I have set aliases in openser.cfg, I have set the hosts file but it still loops. Below you'll find the config and at the end an ngrep output on lo which shows that t_relay() is trying to deliver the invite message from 192.168.178.10:5060 -> 192.168.178.10:5060 in an endless loop until the emssage becomes too big due to increasing # of via headers (see last message at the end of the mail). Just to mention: Openser runs in a virtual environment (VirtualBox Host br0=>tap1=> Client eth0) Can anybody help? What am I doing wrong?
