3.3.13.4 FTP ALG Config
The common port for FTP connection is port 21, and a common ALG monitors
the TCP port 21 to ensure NAT pass-through of FTP. By enabling this function,
when the FTP server connection port is not a port 21, the FTP ALG module will
be informed to monitor other TCP ports to ensure NAT pass-through of FTP.
Choose Advanced > N AT > FTP ALG Config. The FTP ALG Configuration
