Forward Ports for a Synology DS209 device
When you use a Synology DS209 device you may need to forward ports in your router. A port forward allows incoming connection requests from the internet to go straight to a Synology DS209 device.
Routers do not generally allow incoming connection requests from the internet. A port forward can overcome this limitation.
Before You Forward a Port
Before you can forward a port you need to know the following things:
- Your router's IP address.
- Your NAS's internal IP address.
- A list of TCP and UDP ports that need to be forwarded.
How to Locate Your Router's IP Address
To find your router's IP address the easy way you can use our free Router Detector software. It's a part of the Network Utilities suite of tools and it's completely free to use.
