Cannot add SSLVPN server to newly created SSLVPN cluster

SSLVPN server installed successfully. After configuring the SSLVPN server and confirming that all functionality worked fine from the SSLVPN client, a cluster configuration was required for failover purposes. After creating the new SSLVPN cluster, there was no option to add the original SSLVPN server to the cluster. The option to specify the 'Primary Cluster Server' existed but one could not specify any server from the drop down menu.

Make sure that the high bandwidth module is installed on the SSLVPN server. This removes a number of restrictions on the server side (performance and useability).
