Advanced WAN set-up

The advanced WAN configuration detailed below provides the same connectivity as the previous example (Quick WAN set-up). This example allows the connection to be authenticated in both directions using CHAP. The Outgoing Service Name and Password are matched against the Account name and Incoming Password.

Whilst the example details the configuration of WAN service it does not use the WAN service type configuration that was used in the Quick WAN set-up. With a WAN service type set to a Normal service type, the User and RAS items are created and combined into a single entity. This configuration example will detail the manual steps for creating the items which will be combined into a single item equivalent to a WAN type service.

Although the WAN service type used in the previous example (Quick WAN set- up) can be used for CHAP authentication between IPNC systems, the configuration here demonstrates the flexibility of the authentication mechanism. The flexibility of the IPNC means it may be configured to interoperate with the many varied requirements of 3rd party routers.

		Task	Description
Step 1
Attach the WAN cable to the unit and reboot			It is important that, when a new WAN device is
			created in the configuration, the IPNC is re-
			booted with the WAN cable attached.
			Note: Do not attempt to manually create a
			WAN device
Step 2			Once these tasks are completed successfully
Obtain configuration file for Unit1 and perform the
following tasks:			select the newly created User/ Service and
