INTRODUCTION
If you are working regurlarly with Citrix Cloud it may be common knowledge by now that the fundamental connectivity requirement of the Cloud Connectors, on each resource location, is to open up port 443 for outbound connections towards the Internet.
In my experience this is fine and dandy and all, however this won’t be enough for a client’s criteria sometimes. Occasionally we need to jot down the explicit domain names (FQDNs) in which the Cloud Connectors accesses, thus only open up the standard HTTPS port towards these known FQDNs.
This very demand was something I was recently met with so in this post I will share a lesson on pursuing this route.
