Failed to start networking.service on new FreePBX 17 install

Distro Discussion & Help
1

After creating Vultr Cloud Compute Server with Debian 12 x64 as OS
and installing with wget

The networking.service always fails to start.

I set the network settings in System Admin to static with the correct IP address, etc and checked the /etc/network/interfaces.d/enp1s0 file:

auto enp1s0
allow-hotplug enp1s0
iface enp1s0 inet static
address 45.76.75.197
netmask 255.255.254.0
gateway 45.76.74.1

The /etc/network/interfaces file:

#This file describes the network interfaces available on your system

#and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

#The loopback network interface

auto lo
iface lo inet loopback

#The primary network interface

allow-hotplug enp1s0
iface enp1s0 inet static
address 45.76.75.197
netmask 255.255.254.0
gateway 45.76.74.1

The web GUI and phones work but the firewall rules get corrupted.

How can I get networking.service to start? Do I have to disable systemd-networkd?

Every once in a while my v16 Distro would start with disabled Network service after a reinstall.
I suppose it’s the same for v17?

In my case the solution was to make sure that networking.service started correctly before installing FreePBX 17.
