Hello, I have an Installation of 3CX on a VM (HyperV 2012 R2). As a firewall I have a pfSense. I have forwarded the ports as described in the example pfSense configuration provided by 3CX. When I use an online tool to check the ports they show up as opened. However when I do the firewall checker port 5060 isn't reachable. any ideas why that can be?
