Port Forwarding is used to determine which local IP addresses/ports the router
translates to which public IP addresses/ports.
Port Forwarding (PAT)
•
Web operating pages are preset on the web server via Port 80 (HTTP, TCP/IP).
As a result, queries from the Internet must be translated using the public IP
address/port to the private IP address/port 80 for the web server.
•
The port IP address is appended to the web browser address line: <IP
address>:<Port>, e.g.
122.104.2.10:80.
Notes
•
The web browser always uses port 80 unless another port is entered. As a
result, the information in the address line for the web browser is always: <IP
address>:80 and <IP address>, or
122.104.2.10:80
and
122.104.2.10.
•
Ports not equal to 80 are considered more robust against hackers.
•
We recommend using Forwarding Ports from the private range for the port (see
In the example, queries from the Internet to a public IP address (Internet
connection)/Port 80 are forwarded to local IP address
192.168.2.10
(web
server)/port 80.
