The present application discloses an NAT detection method between network nodes, a device, and a storage medium. The method includes: a request node obtains first node information, takes the obtained first node information as payload data of an NAT detection request message or an NAT detection result request message, performs IP packet encapsulation on the NAT detection request message or the NAT detection result request message, performs protection processing on an NAT detection request packet obtained after encapsulation, sends the NAT detection request packet to a response node; and the response node performs deprotection processing on the received NAT detection request packet and obtains the payload data of the NAT detection request message or the NAT detection result request message, compares the obtained payload data with corresponding content in a first IP header of the NAT detection request packet, and determines an NAT detection result according to the comparison result.
