Load sharing NAT Server configuration example
Network requirements
As shown in Figure 61, three FTP servers are in the intranet to provide FTP services for external users.
Configure NAT so that these external users use the address 202.38.1.1/16 to access the servers and the
three FTP servers implement load sharing.
