To be more clearer on the query posted above, we have two services configured i.e. INTERNET & INTRANET. The question here is how to configure the IP traffic for a particular service i.e either for INTERNET or INTRANET service. To be more specific on the details:

We are using CISCO ISG as a gateway for both INTERNET and INTRANET access. We are having a separate billing server connected with AAA server. We are able to successfully bill the authenticated users when they are accessing the INTERNET service (for both prepaid and postpaid).

But our problem is when a user who is authenticated and is accessing the INTRANET pages, he getting charged for that service and amount is deducted from his/her account. To be precise over the solution required:

- Exclude the charging/billing for the user when he accesses INTRANET service.

- At the same time charge/bill him when he is accessing INTERNET service.

Any suggestions regarding CISCO ISG configuration in this regard for how to achieve the above requirement is highly apppreiciated.

Thanks.
