There are two ways you can enable users to login to your Teramind dashboard from outside the local network:
Configure a VPN (recommended option)
You can set up a VPN so that employees can connect to the corporate network from the public internet. This provides some advantages such as more security (VPN communication usually are encrypted) and unlike the method below, you do not need to redeploy the current agents.
Make the server public
You can expose your Teramind server to the internet so that it can be reached from anywhere. You can do this by assigning a public IP address and a valid domain name to the server. You can do this when setting up the connection details while deploying the VM. For more information, see this section on the Teramind On-Premise Deployment Guide: Step 2: Setting Up the IP, Network and the Machine Role(s) > Entering the Connection Details.
Note that, you will need to redeploy the currently installed agents or they will not be able to connect to the new IP address. Alternatively, you can configuring a NAT rule on your router to redirect them.
