I work for a University which implemented CCA last year. One big problem we still encounter with out students is when they have Internet Connection Sharing enabled. When this is active on the student network, a bunch of machines no longer are able to connect to the internet properly. My question is whether or not Cisco can help us create a check to see whether any machine has Internet Connection Sharing enabled, and therefore we can prohibit access until they disable that function. Any responses will be greatly appreciated.
The issue may be due to call back option the callback client (PC or router) dials and connects to the callback server (router) and requests a callback through negotiations. During negotiations, the callback server checks to see if a callback is permitted to this client. If negotiations are not successful for the callback, and the client is not authorized for any other type of session, the client is disconnected. If negotiations are not successful for the callback, but the client is authorized for another type of session, the client remains connected.
