Hi, 1) We have a new Enterasys installation, version "Software: 08.31.03.0011". I try to make a new GuestPortal and I follow the user guide and video "How to configure wireless guest splash for the enterasys wireless solution" and at a certain point (if you follow the wizard), you have to choose for AUTHENTICATION MODE = GUEST PORTAL (that's what the video and the user guide say). Now the problem is that I can't make that choice, I only have "Internal captive portal" and "external captive portal". Why is that ? 2) The current VERY BASIC configuration was done by an engineer but there are some problems with it. There is a guest portal (which we want to change!) and when we connect to it, we get a certificate warning. Isn't it possible to configure the guest portal without HTTPS ? I checked the certificates and there are no certificates configured so I tried to configure one in Enterasys > WIRELESS CONTROLLER > NETWORK > CERTIFICATES and I can make one and save it but when I import it in Enterasys I get an error: Failed to save configuration: Installing the X.509 Certificate operation has failed for topology "Portal Topology". Please check the certificate file integrity. I don't know why I get this error but I don't want that guests get a security warning when they make access. So how can I resolve this problem ? thank you.
