To Set Up Port Forwarding for IPv4 Addresses

Note: To map a port for IPv4, you would enter the range of port numbers that you want
forwarded locally and the IP address for sending traffic to those ports. If you only want a
single port specification, enter the same port number in the start and end locations for that IP
address.
1. Click Create IPv4 to view the IPv4 Entry screen.
2. Do either of the following to set up the External IP Address:
•
Keep the IP Address set at 0.0.0.0 in the External IP Address field and then enter the
port number in the Start Port field. Repeat the same port number in the End Port field.
This allows incoming data traffic on the specified ports from any remote IP address.
• Enter a specific remote IP address of your choice in the External IP Address field and
then enter the specific port numbers in the Start Port and End Port fields. This allows
incoming data traffic on the specified ports from only one remote IP address.
Note: To forward a range of ports, enter the first number of the port range in the Start
Port field and the last number of the port range in the End Port field.
