    Hello everyone,

    I'm new to the 3CX world and I'm wondering if it's possible when installing 3cx on debian, is it possible to apply a firewall rule that will only open ports 9000 - 9500 to 3CX.

    Slightly wary of just opening ports.

    Thanks for any and all replies.
    Dan

    Would you not simply forward the ports, on your router, to the (local IP of) server/PC running 3CX? They won't go to any other device on your network. If it passes through any sort of additional firewall, then those ports would have to be allowed.
