FreePBX 17. Two network addresses even though I set it Static (One IP address and the other Dynamic)s

[Coach25]

I have FreePBX 17 . Does anybody might know why I’m having two IP address. Here are the pictures.

I tried to run cd /etc/sysconfig/network-scripts/ but no such file or directory.

debian is not redhat and by default uses network-manager, use nmcli from a shell

[Coach25]

I’ve installed Network Manager. What do I need to do next?

[dicko]

Read the Manual?

[Coach25]

I’ve have took care of the problem. It was through /etc/network/interfaces. I have figured it out through another advice. Thanks for your help.

It was

auto (interface)
iface (interface) inet static
