Sulaiman Syed Profile: Sulaiman Syed

In the previous entry, i have spoken how to Load Balance CAS using Citrix NetScaler. To finalize the series, i would like to show how to configure Citrix NetScaler for HUB Transport Server. If you have read the previous blog entry, you would realize it is pretty simple. Since they are very similar. I will go about it very briefly and concise.

Image 1 shows the services required to run HUB. we would like one service with protocol TCP and port 25, while the second will be protocol HTTP and port 80.

Once that is done, creating the virtual servers is logical step. We would create one HUB-VIP server that uses protocol TCP and port 25, and second HUB-VIP-Return-HTTP with protocol HTTP and port 80. lastly, we would create HUP-VIP-Return with protocol SSL and port 443. Since the last server using SSL, we would need to do SSL offloading. This will require to use the certificate that was imported. We have used one certificate for all ports, so we will use the same certificate used in previous blog entry. Please note that we don’t any persistence method, while we used Least Connection throughout.
