I have problems to connect a MAC-Server from the wireless-network (WLC-4402-50-K9, Version 5.1.163). The wired clients doesn't have problems to connect to the MAC-Server. The connection works over broadcasts. The wireless-network don't forward this broadcasts. The broadcast-forwarding feature is activated. It is no problem to the MAC-server from the wireless-clients. The hole network is in the same IP-network (one broadcast-domain).
