Change Hostname#

In case you want to change the hostname of your VPN server, you need to follow these steps:

Set the correct hostname;
Make sure DNS is correct;
Obtain new TLS certifcates and install them;
Change the Apache VirtualHost configuration;
Update /etc/vpn-server-api/config.php to make sure hostName (in all profiles) points to the correct name.

We assume you want to rename from vpn.example.org to vpn.example.com. Please adapt the hostname as appropriate.

Hostname#

$ sudo hostnamectl set-hostname vpn.example.com

DNS#

Make sure the new hostname has an A (and AAAA) record to your VPN server IPs.

TLS#

When your DNS is correct you can use Let’s Encrypt to obtain new certificates, or manually obtain them from your CA and install them.

Apache#

Rename /etc/httpd/conf.d/vpn.example.org.conf to /etc/httpd/conf.d/vpn.example.com.conf. Replace all occurences of vpn.example.org with vpn.example.com in the file.

Server#

Modify /etc/vpn-server-api/config.php and look at all hostName entries and change them to the new hostname.

Apply#

Run:

$ sudo vpn-maint-apply-changes

Reboot your system to make sure everything comes back correctly. All should be done now!
