Configuring an IAG VPN gateway

  • Article

Applies To: Intelligent Application Gateway (IAG)

You can publish the Whale Communications Intelligent Application Gateway (IAG) 2007 Network Connector application in order to allow virtual private network (VPN) remote client connections to the internal network. You can configure network adapter settings for Network Connector, including specifying the corporate connection that the Network Connector server should use. In addition, you can change the default listener (port and protocol combination) on which the Network Connector application listens for remote VPN client connections.

Configuring network adapter settings for the Network Connector server

Configure adapter settings as follows:

To configure network adapter settings for the Network Connector server

  1. In the IAG Configuration console, on the Admin menu, click Network Connector Server.

  2. In Network Connector Server, select the Network Segment tab.

  3. In Complementary Data, you can specify alternative network settings. Select Only if Network Configuration is Missing to specify that the remote VPN client should use the settings specified in Network Connection. Alternative settings should only be used if no data is configured for the same item in Network Connection.

  4. In Complementary Data, select Always, Overriding Existing Network Configuration of This Server to specify that the data in Complementary Data is always used, regardless of the configuration of the selected connection. This setting is useful if you want to use a different Domain Name System (DNS), Windows Internet Name Service, or default gateway for connecting clients. Fields that are left empty are ignored.

  5. At the bottom left corner of the Network Connector Server window, select the Activate Network Connector check box. Clearing this option disables an active network connector.

  6. Once you complete the configuration of the server, click OK in the Network Connector Server window in order to activate the network connector.

  7. In the Configuration program, click the Activate icon to save and activate the configuration, and then click Activate in the Activate Configuration window. The configuration settings you have defined are applied to the network connector server. The Network Connector Windows service, Whale Network Connector Server, is started and is set to automatic startup mode.

Notes

  • A dedicated network icon in the Windows System tray indicates that the Whale Network Connector Server service is started.

  • If one or more of the fields are left empty in both the Network Connection and Complementary Data areas, it might result in a limited client session. For example, if no DNS is defined, no DNS services will be available for remote VPN users connecting with network connector.

  • It is recommended that you do not modify the name of the network adapter associated with the IAG Network Connector. If you do change the name and then the adapter is disabled and enabled, the Network Connector server may not start as expected.

Modifying the default network connector listener

By default, Network Connector listens for remote VPN client requests on TCP port 6003. You can modify the default Network Connector protocol and port as follows:

To modify the default Network Connector protocol and port

  1. In the Configuration program, on the Admin menu, click Network Connector Server.

  2. In Network Connector Server, select the Advanced tab.

  3. In Listener, in Type, specify the protocol, and then in Port, specify the port.
