Usage guidelines
This command takes effect only for a device that resides in the private network behind a NAT gateway. The device behind the NAT gateway needs to send NAT keepalives 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.
Examples
# Set the NAT keepalive interval to 5 seconds.
<Sysname> system-view [Sysname] ike nat-keepalive 5
