Port Forwarding (PAT)

· Port Forwarding is used to determine which local IP addresses/ports the router
translates to which public IP addresses/ports.
· Web operating pages are preset on the Web Server via Port 80 (HTTP) or port
443 (HTTPS). As a result, queries from the Internet must be translated using the
public IP address/port to the private IP address/port 80 or 443 for the Web
Server.
· When using PC software ACS790 for remote operation, you must also change
Port 21 (FTP) and Port 50005 (ACS private) from the public to a private IP
address.
· The port IP address is appended to the web browser address line:
<IP address>:<Port>, e.g.
· 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
· Ports not equal to 80 are considered more robust against hackers.
· We recommend using Port Forward Ports from the private range.
In the example, queries from the Internet to the public IP address (Internet con-
nection)/Port 80 is forwarded to the local IP address
Port 80.
