VPN tunnels may be established from a wireless user through a wireless
network without requiring the wireless user to have a relationship with
the wireless network. Instead, the wireless user interfaces with an
authentication, authorization, and accounting service on a VPN host
network. This allows the wireless user to sign on once to gain admittance
to both the wireless network and the VPN host network. The VPN host
network is able to establish accounts on various wireless network
providers to alleviate the need for wireless users to have individual
accounts with the wireless providers. Additionally, a wireless access
point on the wireless network serves as a VPN gateway to interface
between an encrypted session on the wireless network and a VPN tunnel
formed between the wireless access point and the VPN host network. This
allows the wireless access device to participate in a VPN tunnel without
instantiating a VPN client.
