I believe it might be 188.8.131.52.283 that broke this, but it might have also been a prior release. When connecting to the guest network, client connectivity would be intercepted and clients would be shown the Welcome Message, Terms and Conditions and whatnot. With the latest updates, clients are being redirected to the “management” IP address of Unleashed and, since guests do not have access to this IP, Guest Access and the display of the Welcome Message and related is now broken (the captive portal never loads).
What am I missing here? I believe this might have been an issue a while back, but there appears to be a regression in the latest update or two.
