I cannot login to my Loadbalancer WebUI
Manual changes to a loadbalancer configuration cannot be supported by OnApp. OnApp will put in place the necessary configuration for the base Load Balancing functionality offered by the OnApp UI when creating or editing a Load Balancer.
In most cases, the Load Balancer will build and configure on its own and the ports will work. If there is some problem with the cluster nodes not responding, the configuration on the backing virtual servers may need to be checked - see "ARP problem" in the loadbalancer.org docs ( http://pdfs.loadbalancer.org/quickstartguideLBVMv7.pdf )
Please note: Default credentials for load balancers are changed upon LB creation, all management of load balancers should be done through OnApp UI.
OnApp uses Layer 4 / DR mode of the LB exclusively.
