ok.. a little follow-up
i just tested, and yes, i can access the admin interface of the zone director.
my ipad has ip 10.10.70.146, the zone director 10.10.50.1
both are in seperate Vlans. In my firewall i am allowing ALL traffic to go both ways.
in the zonedirector is set the "wireless client isolation" to none.
in the SWAT and SpeedFlex app i entered the 10.10.50.1 ip-address
In the SWAT app i only get 0.0Mbps values (uplink/downlink)
In the SpeedFlex app sometimes gives 0Mbps and 0% pkt-loss on TCP uplink/downlink but also a error "could not configure rx station. possible version incompatibility"
