When I have implemented a Web Portal with authentication through a Radius VNS that has a topology "a" linked to a non authenticated policy, when I had correctly authenticated and I have the Authenticated Policy with a topology "b", the topology change message appears (I know this because I can see it in the Messages Configuration Window). Could in some way overrides this message and goes to the original URL or redirected URL automatically?. This will be a nice feature to big wireless networks and wants to change from a Bridge@EWC to a Bridge@AP Topology and traffic goes locally switched preserving the Web Portal that wireless controller provides. Maybe Doug or his collaborators could answer this question.
