Hello, I am relatively new to 3CX. I have installed a standard installation for test purposes before but haven't done much more with it than that. I am installing 3CX for the first time on a Virtual System. We have a Server running Hyper-V Standalone. I have set up a VM following these instructions: http://www.3cx.com/docs/installing-microsoft-hyper-v/ After doing more research what the next steps are I have become quite confused. I am not sure whether to conduct a standard installation or a Virtual PBX installation. The server is on the local LAN which is protected from the Internet by a pfSense Firewall (So I need NAT). So far I have set Port forwarding rules for ports 5060, 5061, 5090 and 9000-9500. Thanks in advance for any help. It is much appreciated.
