the VPN configuration, in this way, better remote access is achieved.
Next, we will describe the configuration that can be optimized When configuring VPN for small and medium-sized enterprise users. If the network management can pay attention to these configurations, we believe that the stability of VPN can be effectively improved.
1. Select the appropriate VPN Protocol
