Enabling TLS Encrypted Communication for the Remote UI
You can encrypt communication between the machine and a Web browser on the computer by using Transport Layer Security (TLS). TLS is a mechanism for encrypting data sent or received over the network. TLS must be enabled when the Remote UI is used for specifying settings for IEEE 802.1X authentication (TTLS/PEAP) or SNMPv3. To use TLS for the Remote UI, you need to set a key pair and enable the TLS function. Generate or install the key pair for TLS before enabling TLS (Configuring Settings for Key Pairs and Digital Certificates).

In this case, check that the correct URL is entered in the address field, and then proceed to display the Remote UI screen. Starting Remote UI Enabling TLS for e-mailing (MF249dw / MF247dw)If the SMTP server and the POP3 server support TLS, you can enable TLS for communication with these servers (Configuring E-Mail Communication Settings). For more information about the SMTP server and the POP3 server, contact your Internet service provider or Network Administrator. |
