How-To: Port Forwarding On an Airport Extreme & Time Capsule
First of all we need to access our router, for this specific router we need an application called Airport Utility.
Once you download the software and install it, we need to open the application, to do this we open a finder window. As shown in the picture.
Once the finder window opens, in the left column we click on Applications, to access the list of the applications installed on our Mac.
This is how the Airport Utility will show when it opens, click on the router icon to access the router and a window will pop up.
3. Once you are in the window click the “Advanced” gear at the top of the window
4. Click the “IPv6 Firewall” tab
5. Click the “+” to add a new rule
6. In the window that pops up:
- Description: DVR
- IPv6 Address: Enter the IP address of your DVR if you don’t know your DVR’s IP address follow this guide to find out your DVR’s IP address.
- Allow: Specified TCP and UDP ports
- In this case are are going to do this 3 times with the following ports:
- TCP Port(s): 80
- UDP Port(s): 80
- TCP Port(s): 37778
- UDP Port(s):37778
- TCP Port(s): 37777
- UDP Port(s):37777
After you add this ports you are all set.
Check the ports 80, 37777 and 37778.
If you get the success message, you are all set. If not please follow the steps above to be able to open your ports.
Please keep in mind that your Internet Service Provider (ISP) might block some for the ports on your router.
Most residential ISP’s block ports to combat viruses and spam. The most commonly blocked ports are port 80 and port 25.
Port 80 is the default port for http traffic. With blocked port 80 you will need to run your web server on a non-standard port.
If your ISP blocks your port 80 please change the networks settings on your DVR for another port.
