Compal CH6643E User Manual page 36

The ports used by some common applications are:

HTTP: 80

FTP: 20, 21

Secure Shell: 22

Telnet: 23

SMTP e-mail: 25

SNMP: 161
To map a port, you must enter the range of port numbers that should be forwarded locally
and the IP address to which traffic to those ports should be sent. If only a single port
specification is desired, enter the same port number in the "start" and "end" locations for
that IP address.
