1.15.4 Operational precautions when VPN connections are used

This subsection provides the operational precautions when VPN connections are used.

If many VPN-connected PCs for use outside the company are managed simultaneously, the Windows-standard VPN server gets more access, which may cause disconnection of the VPN connections. Therefore, we recommend that you configure the PCs for use outside the company that are to be connected to the VPN so that they can access the VPN server less frequently. An example of this may include specifying a longer polling interval to a higher-level system.
If the host name cannot be resolved between a PC for use outside the company and the management server, the server cannot communicate with the PC. Configure the settings so that the management server starts processing when the PC polls the server.
