Sorry I don't remember the exact subject line. Here's the run down on how to use Microsoft IAS (Internet Authentication Service) to have Cisco devices authenticate using RADIUS. IAS comes in the NT option pack. On the Service tab use the same port numbers that you have configured on the Cisco device. I think 1645 is the default for authentication and 1646 is for accounting. On the Clients tab add in the device that you are setting up RADIUS on. Make sure the shared secrets match. Under the Profiles tab the only attribute name/value pair you need is "Service-Type - Authenticate Only" Jim ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
