Set Up a Port Forward for a Synology DS212j device
When you use a Synology DS212j 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 DS212j device.
Routers do not generally allow incoming connection requests from the internet. By forwarding ports you can work around this limitation.
Before You Forward a Port
Make sure that you know these things before forwarding a port:
- Your router's internal IP address.
- Your NAS's IP address.
- The TCP and UDP ports that need to be forwarded.
Find Your Router's IP Address
The easiest way to locate your router's IP address is to run our free Router Detector utility. The software is part of our Network Utilities suite of tools and it is completely free to use.
If you do not want to run the software, you can follow our Find Your Router IP Address guide.
How To Set Up Port Forwarding for a Synology DS212j device
We have Network Utilities software that can forward ports for you. Since Network Utilities allows you to both forward and un-forward ports easily you can keep your network security maximized, and then forward ports only when you need them.
Port forwarding can also be set up step-by-step by hand. The way to forward a port is:
- Log in to your router.
- Locate the section in your router that deals with port forwarding.
- Type your NAS's IP address into the correct box in your router.
- Put the TCP and UDP ports for a Synology DS212j device in the corresponding boxes in your router.
Frequently you have to reboot your router for the changes to take effect.
