The following tables show the firewall passage directions.

Table B‒2: Firewall passage directions (ACTV mode)
Connection type	Product at server	Port number (example)	Firewall passage direction	Product at client	Port number
Control connection	JP1/FTP	`20125/tcp`	<-	JP1/FTP^#	`ANY/tcp`
Data connection	JP1/FTP	`20124/tcp`	->	JP1/FTP^#	`ANY/tcp`

Table B‒3: Firewall passage directions (PASV mode)
Connection type	Product at server	Port number (example)	Firewall passage direction	Product at client	Port number
Control connection	JP1/FTP	`20125/tcp`	<-	JP1/FTP^#	`ANY/tcp`
Data connection	JP1/FTP	`ANY/tcp`	<-	JP1/FTP^#	`ANY/tcp`

If the product at the client is not JP1/FTP, the port number depends on that product.

ANY means that an available port number assigned by the OS is to be used. In this case, the range of available port numbers depends on the OS.
