Patent abstract
A client attempts to transmit a presence state to a presence server that is behind a firewall of a secure network. If the client is inside the firewall, the presence server instructs resources within the secure network to directly communicate with the client. However, if the client is outside the firewall, then the client must tunnel into the secure network via a Virtual Private Network (VPN) before accessing the resources in the secure network.
