Abstract
A method, system and gateway for remotely accessing an MPLS VPN are provided. In the method, multiple virtual interfaces are established in an SSL VPN gateway, one virtual interface is bound with one VPN, different VPN users are differentiated according to authentication and authorization information of users, and the authentication and authorization information of the users is respectively bound with corresponding VPNs. When the SSL VPN gateway receives a packet sent by a user, an inner label and an outer label are added to the packet according to a VPN instance bound with the user; when receiving a response packet from a resource server, the SSL VPN gateway searches for a VPN instance according to the VPN label, and forwards the response packet to the user through the SSL connection according to the found VPN instance.
