The invention relates to the technical field of network data transmission and discloses a method for achieving gateway dynamic load distribution. The method for achieving the gateway dynamic load distribution mainly includes the following steps: (1) parameters of a gateway cluster are configured; (2) a main gateway is chosen; and (3) dynamic load redirection is conducted, wherein after the main gateway with a virtual router redundancy protocol (VRRP) virtual address receives a security socket layer (SSL) access request of a user terminal, the main gateway selects one gateway of the gateway cluster to serve as a target gateway of the access request and sends a message which is redirected to the target gateway to the user terminal. According to the method for achieving the gateway dynamic load distribution, hardware investment of a load distributor is reduced. The main gateway only needs to be set in the gateway cluster, and then the gateway dynamic load distribution can be achieved. Load balancing of an SSL virtual private network (VPN) gateway cluster is achieved to a certain degree, and the cost is lowered. The problems of the high cost caused by the load distributor and a system performance bottleneck are solved. The load distributor is not adopted, and then the gateway dynamic load distribution can be achieved fast.
