Abstract
An exemplary system and method for using a network access system, such as a virtual private network (VPN), are provided. A user device may have a user session with a home agent. Additionally, an initiating security gateway may be in communication with the home agent, and a terminating security gateway may be in communication with the initiating security gateway via a tunnel (e.g., Internet Protocol in Internet Protocol (IP-in-IP) or Internet Protocol security (IPsec) tunnel). Further, a virtual local area network (VLAN) tag associated with the user session may map to a selector operable in a security policy database. The selector may be used to find a security policy defining an IPsec procedure, and the security policy may be applied to the tunnel. Also, the initiating security gateway may also include a Quality of Service (QoS) module that determines QoS markings for a packet traveling along the tunnel.
