I have been setting up our new wireless environment... employee access and Guest access and folling the "deployment guide for Cisco Guest Access". I am using version 4.26 of the controller code and the Mobility achor control and data paths will come up and stay up for several hours but then they go down. We have all the appropriate ports open in the FW between our inside controller and our DMZ controller. Is there a bug in the 4.26 code? Any ideas would be appreciated.
