[KB7843] Allow external (remote) clients to check into a central ESET PROTECT On-Prem Server

Create a new ESET PROTECT On-Prem policy to allow external (remote) clients to check into a central ESET PROTECT Server

Instead of creating a policy you can redeploy the agent live installer.

Open the ESET PROTECT Web Console.
Create a policy in ESET PROTECT or ESET PROTECT On-Prem.
In the Settings section, select ESET Management Agent from the drop-down menu. In the Connection section, next to Servers to connect to, click Edit server list.
In the Servers window, click Add. In the Host field, type the public fully qualified domain name (FQDN) or public IP address for the ESET PROTECT On-Prem server (adjust the Port number if it was changed from the default value), and click Ok → Save.
Click Assign → Assign.
Select the check boxes next to the groups or specific client computers you want this policy assigned to, and click Ok.
Click Finish.
