Omnissa Unified Access Gateway

Welcome to my Omnissa Unified Access Gateway series, where I show how I set up UAG in my lab. Unified Access Gateway is the appliance that gives users secure remote access to Horizon desktops and applications from outside the corporate network.

The series is written for EUC administrators, consultants and architects, and follows the lifecycle of a UAG deployment: planning and preparation, deployment and configuration, certificates and high availability, and day-to-day operations. New here? Start with one of the learning paths below.

New to UAG: Planning → Prepare → Deploy → Configuration → Routing

Making it production-ready: High Availability → Let’s Encrypt certificate → Upgrades
