Abstract

The present disclosure provides a network communication method and a branch apparatus. The method is applied to a branch apparatus which communicates with a central apparatus through a public network. The method includes: receiving a public IP address sent by the central apparatus after determining that a network address translation, NAT, gateway exists between the branch apparatus and the public network, wherein the public IP address is an internet protocol, IP, address of a target interface included in a target NAT gateway; sending a probe request packet to the target interface, the probe request packet including a destination IP address, the destination IP address being different from the public IP address and in the same network segment as the public IP address; obtaining the number of network apparatuses in a forwarding path for forwarding the probe request packet based on a probe result; sending a NAT keepalive packet to the central apparatus based on a preset period, the NAT keepalive packet including a first time to live, TTL, the first TTL being a sum of the number and a first value. Implementing the method provided in the present disclosure may avoid the impact on traffic forwarding of the central apparatus caused by the NAT keepalive packets.
