To use the secure tunnel, a client system must have access to an IP address, or a fully qualified domain name (FQDN) that it can resolve to an IP address, that allows the client to reach a View Connection Server or security server host. To use the PCoIP Secure Gateway, a client system must have access to an IP address that allows the client to reach a View Connection Server or security server host.

By default, a View Connection Server or security server host can be contacted only by tunnel clients that reside within the same network and are therefore able to locate the requested host.

Many organizations require that users can connect from an external location by using a specific IP address or client-resolvable domain name, and a specific port. This information might or might not resemble the actual address and port number of the View Connection Server or security server host. The information is provided to a client system in the form of a URL. For example:

https://view-example.com:443

https://view.example.com:443

https://example.com:1234

https://10.20.30.40:443

To use addresses like these in View Manager, you must configure the View Connection Server or security server host to return an external URL instead of the host's FQDN.

You configure two external URLs. One URL allows client systems to make tunnel connections. The other allows client systems that use PCoIP to make secure connections through the PCoIP Secure Gateway. You must specify the PCoIP external URL as an IP address, which allows client systems to connect from an external location.

If your network configuration includes security servers, provide external URLs for the security servers. External URLs are not required on the View Connection Server instances that are paired with the security servers.

The process of configuring the external URLs is different for View Connection Server instances and security servers.

For a View Connection Server instance, you set the external URLs by editing View Connection Server settings in View Administrator.

For a security server, you set the external URLs when you run the View Connection Server installation program. You can use View Administrator to modify an external URL for a security server.
