CMS 2.0.3 with OpenVPN

Hello all.

My players connects to my CMSs via OpenVPN. OpenVPN and Xibo-Docker are running on the same debian9 VMs.
My question is about player’s IPs returned in the CMS Displays page.

With all my 1.6, docker-1.8 CMS, the local tun IP player are correctly returned (10.x.x.x)
With the docker2.0.3, all players IPs returned is the same, the Public IP of the debian9 server (195.x.x.x)

Is it normal ? Do I need to install packages or routing rules other ways than the docker default rules ?
