1. A method for providing external access into a secured networked virtualization environment, comprising:

  • performing a first leadership election amongst nodes of the secured networked virtualization environment that elects a leader node that directs an external communication from an external entity to a node within the secured networked virtualization environment;

    assigning a cluster virtual IP address to the leader node, wherein the cluster virtual IP address is a different IP address than an IP address of the leader node;

    generating a reverse tunnel, using a processor of the leader node, based at least in part on the cluster virtual IP address, wherein the external communication from the external entity to the node within the secured networked virtualization environment is sent via the reverse tunnel associated with the cluster virtual IP address;

    identifying failure of the leader node;

    performing a second leadership election amongst the nodes of the secured networked virtualization environment to elect a new leader node;

    assigning the cluster virtual IP address to the new leader node; and

    generating another reverse tunnel by the new leader node to allow the external entity to communicate with the secured networked virtualization environment.
