3CX stopped working - need to open ports

[Vane]

Hi,

There's nothing that's changed on our end and 3CX stopped working out of the blue. I am very technical so I know I made no changes to my router as I am the only one who ever needs to access it.

I briefly chatted with the support team on 3CX chat and they told me I need to open firewall ports (https://www.3cx.com/docs/manual/firewall-router-configuration/)

This worries me for two reasons.

1. I didn't make changes to my router.
2. How does this affect everyone in my remote team now not able to make or receive calls?

I run my 3CX through Google so surely it cannot be dependent on my ports being open on my router and does this mean the ports need to be opened for all my staff working remotely? This becomes a technical nightmare to manage.

Any thoughts?

Thank you.
James

What do you mean by "stopped working"? Can you access the console?

Have you run the 3CXFirewall checker? If all ports do not pass, then that can mean you will have issues. As far as remote access and users, the ports required for these will depend on the devices being used. If they are behind an SBC, or using a 3CX device (App) utilizing the tunnel, then that is going to be a different requirement than a remote STUN device.

Here is a list of the 3CX ports, and their uses.

Have you checked to see if your WAN Address has changed?

Since you run it in Google, you need to open the ports in Google (ie. the firewall controlling the 3CX VM, not the one in your office/home)

Thanks John. That makes sense.
