To add Duo two-factor authentication to your Citrix Gateway with nFactor you’ll configure the Duo Authentication Proxy as a secondary RADIUS authentication server. Primary authentication happens directly between the Citrix Gateway and your Active Directory, LDAP, or other identity store, which enables additional features such as AD password resets.
Before starting, make sure that Duo is compatible with your Citrix Gateway device. Log on to your Citrix Gateway via the web interface and verify that your Citrix Gateway firmware is version 12.1-51.16 or later and your Citrix Receiver or Citrix Workspace clients support 12.1 or later.
Also verify that your Citrix Gateway is licensed for Advanced Authentication Policy. As of Citrix Gateway release 13.0-67.x, the “Standard” license also includes nFactor for Gateway/VPN, while Citrix ADC requires an “Advanced” or “Premium” license to use nFactor.
If you are still using the old version of Citrix ADC and would like to upgrade to UpToDate version, I won’t recommend you upgrade jump by 2 versions (e.g., 10.x to 12.x), because it might happen system crash issues, today, I am going to show you how to upgrade to 11.1.
Citrix ADC is deployed in front of web, application and database servers. It combines high-speed L4-7 load balancing and content switching with application acceleration, data compression, static and dynamic content caching, SSL acceleration, network optimization, application performance monitoring application visibility and robust application security via an application firewall.
As we know, Citrix changed their products name for their product lines, e.g. NetScaler ADC changed to Citrix ADC, today, I am going to show you how to install Citrix ADC VPX 13.0 at Microsoft Windows Server 2019 with Hyper-V.
