Hi. We have problem with connection and download application software to knx lan through wi-fi. We have ruckus ZoneDirector 1200 and 3 Ruckus R500. ip routers connects usually through 3671 port and have some multicast address. And maybe they connecting through tcp and udp. How we can open this ports? In diagnostics knx shows that connection available but when we begin to download anything it tells us that device(ip router) doesn't exist.
