Abstract
Policy enforcement previously available for web proxy access methods is extended and applied to layer 3 packets flowing through VPN channels. With these extensions, a common security policy is possible that is enforceable between VPN proxied access and VPN tunneled access. Equivalent security policy to tunnel based VPN access without comprising the inherent performance, scalability and application compatibility advantages tunnel based VPNs have over their proxy based VPN counterparts.
