Our wlc can't communicate with any host on vlan Z (subnet 192.168.1.0/24). The wlc itself is in a different vlan. All communication to other vlans works just fine. I've temporarly disabled the access-lists for vlan Z, without success. A host in the same subnet as the wlc is able to establish communication with a host in vlan Z.
In the config of the WLC are no specific routes enabled, except for the default gateway of the management interface. I have tested this on a different WLC with the same result, I wasn't able to ping to a host on the 192.168.1.0/24 network.
Yes I am routing to that vlan as I am routing to other vlans. I have tried adding a route to the subnet but I am receiving a message saying, Gateway need to be on service port subnet. According to the manual it is not possible to route traffic to the service port.
