My network does not initialize because the IPTABLES are not found. I do not see the PBX on my router list. I am running the current debian and all maint was current the last I checked. See attached.
If you are upgrading from a previous version of 3CX, IPTables will still be installed. But if you are installing a fresh copy of 3CX, it will use NFTables rather than IPTables.
I did : 1) download the current debian 2) I used RUFUS to move to USB 3) I used DEBIAN recovery 4) I restored with my weekly backup 5) I check maint and my IP addresses blocked 6) Everything connects now... no idea what happened
