Hi Till and Falko, I have a host (Xen domO) with 3 Xen domains on it (3x domU). On the first domU, my iSPConfig3 master server is installed. The 2 other domUs are both ISPConfig3 client servers. When i add a second IP-address on the master server for a website which needs a dedicated IP for SSL, everything works fine. However, when i do the same on one of the ISPConfig slave servers, it doesn't. The vhost file of the site with dedicated IP is ok, but Apache2 shows only "It works". I only have this problem on ISPConfig3 slave servers and i am struggling with this problem for quiet some time already. I also thought it might be a DNS issue, but i have a block with additionial IPs to choose from. It does not matter which IP i choose for the web. The problem remains. Can you reproduce this behavior? I wonder if it's not a bug. Hope you can help me out.
