Parameter
global-addr: Server's public IP address by which external devices can access servers.
global-port: External service port numbers of servers by which the external devices can
access the services provided by servers. If external service port numbers are not

must configure the external service port numbers.
host-addr: IP address of the server on the internal LAN.
host-port: Service port number provided by the server, in the range from 0 to 65,535.
Value of 0 indicates the server can provide any type of services. You can use a keyword
to indicate a frequently used port number. For example, you can use www for WWW
service port number 80, ftp for ftp service port number 21
Note that one command can be used to configure up to 128 internal servers.
global-addr [ global-port ]: Specifies a scope of external service port numbers that
corresponds to the address range of internal hosts. global-port2 must be bigger than
