This tutorial shows how to configure a cluster with two DualShield servers. This cluster is load-balanced by Kemp LoadMaster.

Import SSL Cert

If you are securing your DualShield Servers va SSL then you will need to import your SSL certificates to the LoadMaster

Log into Kemp LoadMaster console and Navigate to "Certificate & Security> SSL Certificates" :

Click "Import Certificate" button on top right.

Here you can import your private/public key, or upload a PFX file.

Once you Save the Certificate file, please select it from the drop down and then click on Use Certificate.

For my test I am just using the inbuilt Self Signed.

Create Virtual Services with TLS Termination

A DualShield server hosts a number of services. Each services works on a specific port. Below is a list of DualShield services and their port numbers:

For my example I am going to create a Virtual Service for Ports 8073 and 8074.Tha Management Console and Single Sign on Ports, respectively. 

Navigate to "Virtual Services > View/Modify Services".

Click "Add New" from either in the main menu or within View/Modify Services screen

Now specify the Virtual IP address you wish to use,  The Port number (In my example I shall use Port 8073) and the Protocal will be TCP

Click on Add This Virtual Service on the bottom right.

This will take you to the Layer 7 properties screen...

Please select the options as follows

Basic Properties set the Service type to HTTP-HTTPS/2-HTTPS (see picture above)

Standard Options set Mode in Persitance Options to Source IP (See picture below)

SSL Properties , enable SSL Accelration  and check  Reencrypt.

In the Certificates section Highlight the certificate you imported earlier and move it accross to the right hand box, then click Set Certificates.

Advanced Properties in the section Add HTTP Headers select X-Forwarded-For (No Via) From the drop down

Real Servers.  Click on teh Add New Button

Type the IPv4 Address of the Primary DualShield Server

The Port  should have autocompleted with the port number you specified when creating the virtual service (see above)  If it doesn't please add the port number you are referring to.

Click the Add This Real Server button on the right hand side.

Click OK on the confirmation message at that appears at the top.  Repeat the process to Add the IP address of the Secodary DualShield Server.

The configured Real Servers will appear on the bottom left hand side.

Once completed click on Back button.  The list of real IP's will appear as below.

Click  Virtual Services->View/Modifies Services in the main menu again and Add New.

Repeat the steps above, again to add another Virtual Service tied to another Port.

In my example I have only added Services for ports 8073 and 8074.

Modify DNS

Modify your DNS entry so that the IP for your DualShield Server's FQDN points to the virtual IP you set up in Kemp Load Master.
