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.
