1. First you will need a computer/laptop to be connected to one of the LAN Ethernet ports.
NOTE: Changing the Port Forwarding values can be performed under Wireless, however
we do not recommend it.
2. Proceed to open an Internet Browser and login to the DIR-300 Web Configuration.
NOTE: Instructions are on the Technical Support Knowledge Base if you are unsure on
how to login to the Web Configuration.
3. Before proceeding, you will need to know the actual Ports that your application
requires.
You will also need to know the IP Address of the computer/laptop that you would like the
Ports to be binded to. It is not recommended to have a Port Forward entry on a connected
computer/laptop without a Static IP Address assigned and or a DHCP Reservation setup
on the DIR-300. This guide will advise on the DHCP Reservation setup. To ensure your
computer/laptop always get the same IP Address, see below:
Click on SETUP > LAN Setup menu
