SSL VPN network extension connects the end-user system to the corporate network with access controls based only on network layer information, such as destination IP address and port number. So, it provides safe communication for all types of device traffic across public networks and private networks, also encrypts the traffic with SSL protocol. +The remote user will use the anyconnect client to connect to the router and will receive an IP address from a VPN pool, allowing full access to the network. + +.. note:: All certificates should be stored on VyOS under /config/auth.
