Adding a port to 3CX firewall

[Starburst]

I installed the Debian based Linux ISO image, but can not get port 5666 for monitoring to open.

Standard commands look like they worked, but port is still closed.

Any help would be appreciated.

Thanks,
David

Run:
iptables -A INPUT -p tcp --dport 5666 -j ACCEPT

You will need to do this after every reboot unless you save the iptables rules. I think that command is something like iptables-save > /etc/iptables/rules.v4
