http to https redirect for KEMP Loadmaster

More and more customers are going for KEMP Loadmaster as reverse proxy. Often the question about http port 80 redirect inside KEMP Loadmaster to https 443 and then to a realserver who runs 8080 or other ports.

Then just follow these steps
To redirect from HTTP to HTTPS, follow the steps below in the LoadMaster Web User Interface (WUI):


  1. Create a Virtual Service on the IP address you use for HTTPS on port 80. This service will act as a redirector and does not need Real Servers.
  2. Once created, on the Virtual Service modify screen, expand the Advanced Properties section.
  3. In the Not Available Redirection Handling section, select 302 Found as the Error Code.
  4. Enter the URL to redirect to in the Redirect URL text box. Click Set Redirect URL. You may use the wildcards %h and %s to represent the requested hostname and Uniform Resource Identifier (URI) respectively.
then under redirect url add https://servicedesk.domain.com

After the public DNS has been created and the FW is open for port 80 for this service well then KEMP will do it's magic.

You can try it from your browser and type in: http://servicedesk.domain.com and you will end up in https://servicedesk.domain.com

Office web app server (WAC) and HLB

One of my customer who I have build a Skype for Business as a service for are running KEMP Loadmaster in a HA environment.
One of the things we did was to HLB WAC server. This is how we did it:
1. install the frist WAC server and with a certificate
2. Create the farm with external and internal URL https://owaweb.domain.com/hostring/discovery
3. check the farm and that the service running
4. Then install the second WAC server with the same certificate as on the frist one
5. Get the machine to Join the farm by this Command
New-OfficeWebAppsMachine -MachineToJoin wac1.domain.com
More about it here: 
https://blogs.technet.microsoft.com/jenstr/2013/03/18/creating-an-office-web-apps-server-2013-farm-with-2-machines/

Make sure that its all in the S4B topology, the farm is defined. Also the internal and external DNS records for the farm, pointing to KEMP Loadmaster. Open for port 443 in the Firewall


On the  KEMP Loadmaster just use the template, then Add the VS using public ip and then connect to the OWA servers on your internal network and let KEMP do the LoadBalancing.


After testing the solution where we duing a powerpoint presentation we did not have downtime, just a small freeze for 1 second for the presenter who run the powerpoint in Skype for Business.
