Horizon can be used with the minimum Horizon protocols listed above. There are a set of optional protocols that can are supported and are described below.

In all of the forward rules examples, the IP address used by UAG 1 to connect to UAG 2 is 192.168.2.101. If NAT is in use between DMZ 1 and DMZ 2, this will be that NAT'd address used in DMZ 1.The forward rules configuration settings for UAG 1 can either be applied by specifying the rules in the [General] section of the PowerShell.INI file or can be specified in the Deploy OVF Template wizard if doing a manual deployment.
Note: Multiple forward rules must be specified as a set of comma separated rules on a single line.
For more information on this refer to the standard Unified Access Gateway document Deploying and Configuring Unified Access Gateway.

HTTP TCP Port 80

As a convenience for users, Unified Access Gateway supports automatic redirect of port 80 HTTP requests to HTTPS URL on port 443. This can be used so that a user does not need to enter https:// before the hostname in a browser URL or in the Horizon client. To allow this capability, TCP port 80 must be allowed through FireWall 1.There are no additional configuration steps needed on Unified Access Gateway.

Blast Extreme on TCP Port 8443

Blast Extreme TCP can be used on TCP port 8443 as an alternative to TCP port 443. Allow TCP port 8443 through FireWall 1 and FireWall 2. Add a TCP forward rule to UAG 1 so that TCP connections on port 8443 arriving from the Internet to UAG 1 will be forwarded to UAG 2. 
forwardrules=tcp/8443/192.168.2.101:8443

Blast Extreme on UDP Port 8443

Blast Extreme UDP can be used on UDP port 8443. Allow UDP port 8443 through FireWall 1 and FireWall 2. Add a UDP forward rule to UAG 1 so that UDP datagrams on port 8443 arriving from the Internet to UAG 1 will be forwarded to UAG 2. 
forwardrules=udp/8443/192.168.2.101:8443

UDP Tunnel on UDP Port 443

Allow UDP port 443 through FireWall 1 and FireWall 2. Add a UDP forward rule to UAG 1 so that UDP datagrams on port 443 arriving from the Internet to UAG 1 will be forwarded to UAG 2. 
forwardrules=udp/443/192.168.2.101:443

PCoIP on TCP Port 4172 and UDP Port 4172

To support PCoIP 
forwardrules=tcp/4172/192.168.2.101:4172,udp/4172/192.168.2.101:4172
