lot of practical, in addition to the solutions provided by some vendors, A more effective way is to use free software to complete this task. This includes the NAT Implementation Method in the Linux virtual server project, or the revised version of natd under FreeBSD. Generally speaking, this software method is used to implement address translation. The bandwidth limit of the central server Load

balancing 1. network load balancing allows you to spread incoming requests to up to 32 servers, that is, you can use up to 32 servers to share external network request services. Network Load Balancing Technology ensures that they can respond quickly even when the load is heavy. 2. Only one IP address or domain name must be provided for external network
