To set up Offsite MFA logon, you need to complete the following steps
In the DualShield Admin Console, find the computer logon agent in Authentication | Agents

Click its context menu

Select "Edit"

Enter the Agent's Public URL in the format "https://fqdn:14294/xmlrpc", e.g. https://anywhere.deepnetmfa:.com14294/xmlrpc
Click Save.
Important: if you have multiple Computer Logon Agents, then repeat the steps above on every Windows Logon Agent.

You need to configure your corporate firewall so that port 12841 is accessible from the Internet, and that the traffic from the Internet coming to this port is forwarded to the server machine where the Computer Logon Agent is running. Please note that the DualShield Computer Logon Agent is a TCP service, not an HTTP service, although the Agent Public Agent needs to be prefixed with "https://"
