Make services available in the SSL VPN Portal

SSL VPN Portal Services map external URLs to HTTP-based services in the protected network.

SSL VPN Portal Service elements contain settings that define how the internal URLs of the HTTP-based services are translated to external URLs. URL translation makes sure that all traffic to registered web resource hosts is routed through the SSL VPN Portal. End users can access the SSL VPN Portal Services through the SSL VPN Portal, or directly through web browser bookmarks.

SSL VPN Portal Service Properties dialog box

Use this dialog box to define the properties of an SSL VPN Portal Service element.

Option Definition
General tab
Name Specifies a unique name for the element.
Note: The name must only contain letters, numbers, dashes (-), and underscores (_).The name cannot contain spaces.
Link Translation Specifies how incoming connections are routed to services in the protected network.
  • URL Rewrite — A URL prefix that corresponds to a service in the protected network is added to the URL.

    Incoming connections are routed to the service in the protected network based on the URL prefix. HTTP responses from the servers in the protected network are rewritten to change the outgoing URLs. This option does not require any additional DNS entries.

  • DNS Mapping — Incoming connections to the SSL VPN Portal are translated to an internal host running on a specific port.

    This option requires a DNS entry for each service in the protected network.

  • Freeform URL — Users can manually enter a URL in the SSL VPN Portal in addition to selecting a predefined service.

    Instead of having to configure every portal service individually, you can create a list of allowed URLs and certificates or CAs.
Disable Client-Side Rewrite When selected, disables client-side URL rewriting. Select this option only if client-side URL rewriting does not work as expected and you need to revert to a previous working configuration.

Client-side URL rewriting improves compatibility when JavaScript is used to dynamically construct URLs. Disabling the rewriting changes the way the URLs in JavaScript are handled and often breaks the links within JavaScript.

Note: Client-side URL rewriting must be enabled to connect to some services, such as Sharepoint and Office365, through the SSL VPN Portal.
