You might experience connection problems between View Client and a security server or View Connection Server host when the PCoIP Secure Gateway is configured to authenticate external users that communicate over PCoIP.

View clients that use PCoIP cannot connect to or display View desktops. The initial login to a security server or View Connection Server instance succeeds, but the connection fails when the user selects a View desktop. This issue occurs when the PCoIP Secure Gateway is configured on a security server or View Connection Server host.

Note

Typically, the PCoIP Secure Gateway is leveraged on a security server. In a network configuration in which external clients connect directly to a View Connection Server host, the PCoIP Secure Gateway can also be configured on View Connection Server.

Problems connecting to the PCoIP Secure Gateway can occur for different reasons.

Windows Firewall has closed a port that is required for the PCoIP Secure Gateway.

The PCoIP Secure Gateway is not enabled on the security server or View Connection Server instance.

The PCoIP External URL setting is configured incorrectly. You must specify this setting as the external IP address that View clients can access over the Internet.

The PCoIP External URL or secure tunnel External URL is configured to point to a different security server or View Connection Server host. When you configure these two external URLs on a security server or View Connection Server host, both external URLs must be addresses for the current host.

The View client is connecting through an external web proxy that has closed a port required for the PCoIP Secure Gateway. For example, a web proxy in a hotel network or public wireless connection might block the required ports.

The View Connection Server instance that is paired with the security server on which the PCoIP Secure Gateway is configured is version View 4.5 or earlier. The security server and paired View Connection Server instance must be View 4.6 or later.

Check that the following network ports are opened on the firewall for the security server or View Connection Server host.

Port

Description

TCP 4172

From View Client to the security server or View Connection Server host.

UDP 4172

Between View client and the security server or View Connection Server host, in both directions.

TCP 4172

From the security server or View Connection Server host to the View desktop.

UDP 4172

Between the security server or View Connection Server host and the View desktop, in both directions.

In View Administrator, enable the PCoIP Secure Gateway and make sure that the PCoIP External URL is configured correctly.

a

Click View Configuration > Servers.

b

Select the security server or View Connection Server instance and click Edit.

c

Select Use PCoIP Secure Gateway for PCoIP connections to desktop.

The PCoIP Secure Gateway is disabled by default.

d

In the PCoIP External URL text box, make sure that the URL contains the external IP address for the security server or View Connection Server instance that View clients can access over the Internet.

Specify port 4172. Do not include a protocol name.

For example: 10.20.30.40:4172

e

Make sure that both the PCoIP External URL and secure tunnel External URL are the addresses that client systems use to reach this host.

For example, if you configure a View Connection Server host, do not specify the PCoIP External URL for this host and the secure tunnel External URL for a paired security server.

f

Click OK.

If the user is connecting through a web proxy that is outside of your network, and the proxy is blocking a required port, direct the user to connect from a different network location.

Make sure that both the security server and the paired View Connection Server instance are View 4.6 or later.
