When running in Windows or Linux, only allow connections to ERemoteServer from trusted hosts and block all others.
When running the Windows operating system, configure Localhost communications (127.0.0.1) between ERemoteServer and Axeda Builder. Refer to PTC knowledge article CS360255
Configure the Axeda agent for the authentication information required to log in to the Axeda Deployment Utility. Refer to PTC knowledge article CS360255
PTC recommends upgrading the Axeda Desktop Server (ADS) to Version 6.9 build 215

The Axeda agent loopback-only configuration is only available in Version 6.9.1 and above. Hence, upgrading to Axeda agent 6.9.1 or above is required.
