VMware Horizon External access

[HussamRabaya]

i have strange issue with Horizon 7.10 , where i can connect to windows 10 vDesktops from my local Lan , but once  i go to same desktop in same pool and try to connect externally from internet , windows console open and then stuck in apply DEM or sometime in Appvolumes applying configuration and windows stuck here

knowing that im using UAG 3.8 with horizon 7.10 and smart policy applied to disable some featuers if client location is extrenal

any idea what could be the issue ?

What are the features disabled thru Smart Policy?

To allow external client devices to connect to a Unified Access Gateway appliance within the DMZ, the front-end firewall must allow traffic on certain ports. By default the external client devices and external Web clients (HTML Access) connect to a Unified Access Gateway appliance within the DMZ on TCP port 443. If you use the Blast protocol, port 8443 must be open on the firewall, but you can configure Blast for port 443 as well.

Mainly look for the below network ports between the UAG and VDI Desktops subnets are open in firewall.

22443	TCP and UDP	Unified Access Gateway	Desktops and RDS Hosts	Blast Extreme
4172	TCP and UDP	Unified Access Gateway	Desktops and RDS Hosts	PCoIP (optional)
32111	TCP	Unified Access Gateway	Desktops and RDS Hosts	Framework channel for USB Redirection
9427	TCP	Unified Access Gateway	Desktops and RDS Hosts	MMR and CDR
