Note:
After you configure the internal FTP server, the FTP clients of the public network can
access the internal FTP server of the private network in the Passive manner. If the FTP
client of the public network wants to access the internal FTP server of the private
network in the Port manner, only FTP servers using port 20 as the data port are
supported. If the internal FTP server does not use port 20 as the data port, you must
configure the NAT rules corresponding to the internal FTP server to enable the services
being provided smoothly and data connection and controlling connection using the
same public address for NAT. That is, one address pool is bound to the NAT rule, and
the address of the address pool and the public address of the internal FTP server are
overlapped.

1.3.1 Configuring an Address Pool

An address pool is a collection of consecutive public IP addresses. If its starting IP
address and ending IP address are the same, there is only one address in the address
pool.
During address translation, the NAT server selects an IP address from the address pool
to be the translated source address. Use the nat address-group command to
configure an address pool.
