Found the problem.
Had to fill out the Address, don't know why, but tor fetched a different IP
The used system has only one configured interface:

mike at torhost:~$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
     inet6 ::1/128 scope host
        valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
state UP qlen 1000
     link/ether 00:50:56:b8:8b:37 brd ff:ff:ff:ff:ff:ff
     inet MY_PUBLIC_IP/24 brd 81.2.236.255 scope global eth0
     inet6 fe80::250:56ff:feb8:8b37/64 scope link
        valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
     link/ether 00:50:56:b8:9f:4c brd ff:ff:ff:ff:ff:ff

     link/ether 00:50:56:b8:68:52 brd ff:ff:ff:ff:ff:ff
