ONFIGURATION
FTP ALG Configuration specifies a non-standard FTP port for passthrough
traffic. The standard port for FTP connections is TCP port 21, and the router
monitors port 21 to ensure the NAT passthrough of FTP. When the FTP
server port is not 21, you must specify the TCP port to ensure NAT
passthrough of FTP.
