Usage guidelines

This command takes effect when the device resides in the private network behind a NAT device. The device must send NAT keepalive packets regularly to its peer to keep the NAT session alive, so that the peer can access the device.

The NAT keepalive interval must be shorter than the NAT session lifetime.
