[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?
Here is my conf:
