Setting Up a Port Forward for a Synology DS212 device
When you use a Synology DS212 device you might need to forward some ports in your router. A port forward allows incoming connection requests from the internet to go straight to a Synology DS212 device.
Routers are not designed to allow incoming network requests. By forwarding a port you can overcome this limitation.
Before You Forward a Port
Make sure that you know these things before forwarding a port:
- The internal IP address of your router.
- The internal IP address of your NAS.
- Each of the TCP and UDP ports that you need to forward.
How to Locate Your Router's IP Address
We have free Router Detector software to help you find your router's IP address. It is part of our Network Utilities suite of tools and is free for you to use it.
We have a guide you can follow Find Your Router IP Address if you don't want to run the software.
Setting Up a Port Forward for a Synology DS212 device
A smart way to forward your ports is to use Network Utilities. Our Network Utilities software allows you to add port forwards and also remove them when you no longer need them to maximize your network security.
You can also choose to set up port forwards manually. The normal process for forwarding a port is:
- You can start by logging in to your router.
- Locate your routers port forwarding section.
- Put the IP address of your NAS in the proper box in your router.
- Put the TCP and UDP ports that you are forwarding for a Synology DS212 device in the correct boxes in your router.
You probably will need to reboot your router for the changes to take effect.
