Configuring the IKEv2 NAT keepalive feature

About the IKEv2 NAT keepalive feature

Configure this feature on the IKEv2 gateway behind the NAT device. The gateway then sends 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.

This feature takes effect after the device detects the NAT device.
