I'm trying to install a ISPConfig3 multiserver setup where the control-panel is on WAN and all other servers are on LAN but I can't get the slaves to sync. Any ideas what is wrong? All the slave DB's can access master and on master ISPC panel you can see the slave clearly registered. I thought it has something to do with split DNS but now I'm thinking this is actually a problem with our FW cluster. When I do "netstat -tapn |grep mysql" on master ISPC I can see that mysql is connected to one of the FW cluster nodes that has different IP address than is recorded on dbispconfig. Now what?
