You should reboot to allow the changes to take effect.
If it is called something else in your system, obviously make allowances for this and adjust things as necessary.
If you have successfully changed the IP address, and you can gain access via SSH to the server, but the Access Server web services are not responding, it is possible you had your Access Server configured to listen to a very specific IP address, and if you have changed this, then the Access Server web services won't start.
In some situations if the DNS server needs to be changed and you have things set statically you'll need to edit /etc/and update it to have the correct DNS server.
Without a working DNS server you'll be able to ping IP addresses like 8.8.8.8 on the Internet, but not be able to resolve and ping addresses like Another important thing to note here is that in our situation shown above we have only one network interface and it is called ens192.
Messing with the network interface settings could mean you lose network access to this system if you make a mistake.
So be aware of this and either beforehand make a backup of your Access Server settings or make a snapshot if possible in your hypervisor, or see if can get access to the (virtual) console to make corrections afterwards.
This is pretty useful when you need multiple IP addresses but you have only one network card.
The program dhclient will get you the IP to the given interface using the Dynamic Host Configuration Protocol (DHCP).
Means you will lose that IP and will get an other different IP assigned after reboot.
To make this IP permanent we have to edit the configuration files.
