Status: openser compiled, including mysql openser working with mysql (registering) openser server has two ethernet ports with one public and one private IP rtpproxy is running without any parameter

7311 is eyebeam on local desktop 7312 is gizmo on the same local desktop 7111 is a grandstream remote, behind a nat

Openser adminstrator shows all three phones as registered with following sip addresses: sip:7111@192.168.10.91 sip:7311@192.168.250.108:42800;rinstance=f17a00051f63a625 sip:17476063396@proxy01.sipphone.com:5060 <=== that should be 7312@192.168.250.108

Internal calls: call from 7312 to 7311 works. call from 7311 to 7312 ends up at a voicemail box (most likely gizmo problem) call from 7311 to 17476063396@proxy01.sipphone.com ends up at the voicemail box

External calls: call from 7311 (local phone) 7111 (remote phone behind NAT) does not work, see the ngrep info below. Looking at the output I feel that the nathelper is not working. As I understand the documents, the address should be replaced with an public IP address, but it uses my servers internal ethernet port (192.168.250.41) 5.32.86.166 in alt1 is the IP address of my Hamachi network. I have no idea, why this one shows up here.
