Pre-deployment Checklist and Tasks
Configure server certificates and CA certificates on the Expressway-E
Remote and mobile clients must verify (by validating the server certificate) the identity of the Expressway-
E to which they are connecting. To do this, in their list of trusted CAs, the clients must have the certificate
authority that was used to sign the Expressway-E's server certificate.
This design requires secure communications between Expressway-C and Expressway-E, as well as
between Expressway-E and endpoints located outside the enterprise.
