network. User U sends an SSL request to destination server D (1), via the Zyxel Device, Z. D replies (2); Z
intercepts the response from D and checks if the certificate has been previously signed. Z then replies to
D (3) and also to U (4). D’s latest certificate is stored at myZyxel (M) along with other server certificates
and can be downloaded to the Zyxel Device.
