Abstract: Methods and systems for forwarding data between a first network element and a terminal at a management server, comprising the steps of receiving a request from the terminal to communicate with the first network element during a first data session; determining whether a first connection has been established with the first network element; establishing the first connection with the first network element if the first connection has not been established with the first network element; and forwarding data between the first network element and the terminal using the first connection during the first data session.

Abstract: The present invention discloses methods and systems for a VPN gateway to establish virtual private network (VPN) connections with at least one other VPN gateways. The VPN gateway determines that it is classified into a first VPN gateway group by a VPN management server, and the VPN gateway determines which other VPN gateways belong to the same first VPN gateway group. The VPN gateway then determines and sends information about the number of remaining possible VPN connections (RPVPNC) to the VPN management server, such that the VPN management server is able to send a first configuration to the first VPN gateway. The first VPN gateway is then configured according to the first configuration, and the first VPN gateway establishes VPN connections with other VPN gateways based on VPN connection topology, configuration, and number of RPVPNC of the first VPN gateway and other VPN gateways.

Abstract: The present invention discloses methods for establishing Virtual Private Network (VPN) connections among a plurality of VPN gateways at a VPN management server. The VPN management server determines VPN gateways belonging to a first VPN gateway group and also determines the number of possible VPN connections for each VPN gateway of the first VPN gateway group. Configuration for each VPN gateway of the first VPN gateway group is determined based on, at least in part, a VPN connection topology and the number of VPN connection license(s). Each VPN gateway of the first VPN gateway group is configured according to the configuration and a plurality of VPN connections is established based on, at least in part, the configurations.
