•Advanced settings and component installation tree have been streamlined to align with the structures used in other ESET security products.

•eShell commands have been modified to reflect the updates and consolidation of advanced settings.

•eShell status commands are now organized within a single context and sub-context.

•Limit incoming RDP connections—RDP access restriction feature for ESET Mail Security without a firewall component.

Note

If you perform an attended fresh installation locally on the server, the Limit incoming RDP connections to is set to Trusted zone by default. If you perform an installation remotely over RDP, the Limit incoming RDP connections to is set to All networks by default. This setting is meant to be temporary and to prevent your RDP connection from being cut off until you configure the Trusted zone.

In both cases, we recommend configuring the Trusted zone to include networks, IP addresses, or IP address ranges from which you specifically allow RDP connections to the server. Go to Network access protection > IP sets and edit Trusted zone IP set. After configuring the Trusted zone IP set to your needs, change the Limit incoming RDP connections to use the Trusted zone from the previous All networks setting to secure your server and take advantage of the RDP access restriction feature while having the RDP fully functioning within your company networks.
