How do I open ports on my router?
To allow traffic from the internet to enter your local network, you will need to open up
ports or the router will block the request.
Step 1
Open your web browser
and enter the IP Address of
your D-Link router
(192.168.0.1). Enter username
(admin) and your password
(blank by default).
Step 2
Click on Advanced on
top and then click Virtual
Server on the left side.
Step 3
Check Enabled to
activate entry.
Step 4
Enter a name for your virtual server entry.
Step 5
Next to Private IP, enter the IP Address of the computer on your local
network that you want to allow the incoming service to.
Step 6
Choose Protocol Type - either TCP, UDP, or both. If you are not sure, select
both.
Step 7
Enter the port information next to Private Port and Public Port. The private
and public ports are usually the same. The public port is the port seen from the WAN
side, and the private port is the port being used by the application on the computer
within your local network.
Step 8
Enter the Schedule information.
Step 9
Click Apply and then click Continue.
Note: Make sure DMZ host is disabled. If DMZ is enabled, it will disable all Virtual
Server entries.
Because our routers use NAT (Network Address Translation), you can only open a
specific port to one computer at a time. For example: If you have 2 web servers on
your network, you cannot open port 80 to both computers. You will need to configure
1 of the web servers to use port 81. Now you can open port 80 to the first computer
and then open port 81 to the other computer.
