mobile electronic device (10) and the VPN gateway (122) through the
communications link (130), the first VPN connection (136) using key-based
encryption to protect data exchanged therethrough. While the first VPN
connection (136) is established, a second VPN connection (138) is
established between the mobile electronic device (10) and the VPN gateway
(122) through the communications link (130), the second VPN connection
(138) using key-based encryption to protect data exchanged therethrough.
