    Hi There,

    we tested a virtual pbx hosted by OVH and this works great.
    https://www.3cx.com/docs/virtual-pbx-ovh/

    Our problem is the firewall on the linux system. In general all ports are open on the VPS server.
    I try to make a script for iptables and it seemd to work. Calls inbound/outbound, STUN all is working.
    But the firewall checker does not work.

    So, i was wondering if anybody has a working script for iptables, where the firewall checker and everything is working.
    Unfortunately 3CX does not provide a script.

    Thanks in advance.

    Hi,

    we used the installation provided in my link.

    Is there any chance that you can give me the iptables?

    Best regards

    Hi there,

    i got the iptables form the linux ISO and could successfully restore them into my cloud pbx.

    Now the firewall check is working fine.

    Best regerads

    Hello YiannisH,

    We have also set up a test virtual pbx on OVH and this thread brings up quite a good question. As OVH provide the ISO for these virtuals is there anything else from the 3CX ISO, like the aforementioned firewall rules, that need to be "tweaked" after we have built the phone system?

    I look forward to hearing from you.

    Tony

    P.S. Ittogo, any chance you could document how you extracted and applied the firewall rules?
