Abstract
A method of communicating with a remote server via a client, the method comprises the steps of: allowing encapsulated data to be transmitted from the client and towards a remote server via a VPN; attempting to gain access to, or to increase access to, a private network with unencapsulated data and outside of the VPN; identifying a captive portal that restricts access to the private network; allowing receipt of signaling with unencapsulated data outside of the VPN that causes an authentication server associated with the captive portal to permit access or increase access to the private network; and transmitting encapsulated data from the client to the remote server via the VPN and over the private network after the authentication server grants access to the private network.
