Server 2.x

Deploying on CentOS / Red Hat Enterprise Linux#

For simple one server deployments and tests, we have a deploy script available you can run on a fresh CentOS (or Red Hat Enterprise Linux) 7 installation. It will configure all components and will be ready for use after running!

An additional script is available after deployment:


We test only with the official CentOS Minimal ISO and the official Cloud images. For Red Hat Enterprise Linux we test with the official Red Hat Enterprise Linux ISO, e.g. rhel-server-7.5-x86_64-dvd.iso.

If you have a more complicated setup, we recommend to manually walk through the deploy script and follow the steps.

Base Deploy#

Perform these steps on the host where you want to deploy:

$ curl -L -O
$ tar -xzf v2.tar.gz
$ cd deploy

Run the script (as root):

$ sudo -s
# ./

Specify the hostname you want to use for your VPN server. The recommended hostname SHOULD already be the one you want to use… If not, set the hostname correctly first.

NOTE: you can NOT use localhost as a hostname, nor an IP address!

NOTE: by default there is NO firewall for the traffic between VPN client and VPN server. So if you have SSH running on your server, the clients will be able to connect to it when you don’t take additional steps! Look here.

NOTE: if you want to use the development repository, use:






See PROFILE_CONFIG on how to update the VPN server settings.


Username & Password#

By default there is a user demo and admin with a generated password for portal access. Those are printed at the end of the deploy script.

If you want to update/add users you can use the vpn-user-portal-add-user. Provide an existing account to update the password:

$ sudo vpn-user-portal-add-user
User ID: foo
Setting password for user "foo"
Password (repeat):

You can configure which user(s) is/are an administrator by setting the adminUserIdList option in /etc/vpn-user-portal/config.php, e.g.:

'adminUserIdList' => ['admin'],


It is easy to enable LDAP authentication. This is documented separately. See LDAP.


It is easy to enable RADIUS authentication. This is documented separately. See RADIUS.


It is easy to enable SAML authentication for identity federations, this is documented separately. See SAML.


It is possible to enable 2FA with TOTP.


If you want to restrict the use of the VPN a bit more than on whether someone has an account or not, e.g. to limit certain profiles to certain (groups of) users, see ACL.


Web Server Certificates#

By default a self-signed certificate is used for the web server. You can install your own certificates, and tweak /etc/httpd/conf.d/ to point to them, or use Let’s Encrypt using the script mentioned below.

Let’s Encrypt#

Run the script (as root) from the documentation folder:

$ sudo -s
# ./

Make sure you use the exact same DNS name you used when running!

After completing the script, the certificate will be installed and the system will automatically replace the certificate before it expires.

Port Sharing#

If you also want to allow clients to connect with the VPN over tcp/443, see Port Sharing.

Let’s Connect! Branding#
