About setting the FTP server to transmit data in passive mode under a common Broadband Router

To solve the problem of setting up an FTP server to transmit data in passive mode on a general Broadband Router, I am sorry to have a problem with setting up an FTP server on a Broadband Router. The following is a summary of the configuration of www.2cto.com: 1. A fixed public IP address is connected to a Broadband Router, And the LAN can access the Internet normally. 2. A server 192.168.1.10 in the LAN is used to build a server based on Serv-U. problems may occur during normal LAN access: according to the usage instructions of the Broadband Router, Port 20 and port 21 are mapped to 192.168.1.10, and then FTPFXP is used to connect the public IP address of the Broadband Router from the Internet. The login is normal, but the directory cannot be listed; use the FTPFXP active mode. Www.2cto.com the author is too lazy to type. The description is as follows: 1. Set "virtual server" in the Broadband Router.

2. Set the PASV port range of the local server in Serv-U.

3. Enter the public IP address in the IP address used in passive mode.

Done!
