Advanced Port Forwarding Page
This page allows you to run a publicly accessible server on the LAN by specifying the
mapping of TCP/UDP ports to a local PC. This enables incoming requests on specific port
numbers to reach web servers, FTP servers, mail servers, etc. so that they can be
accessible from the public Internet.
A table of commonly used Port numbers is also displayed on the page for your
convenience. 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.
