What should I do after setting VPN server on Synology NAS?

As we knew, Synology NAS provides a VPN function so that users can access resources shared within the local area network of your Synology NAS remotely and securely.

In general, Synology provides PPTP/L2TP/OpenVPN Server, after enabling it, you need to do a port forwarding on your wireless Router. Here are some key points when you configure it on your Router.

1. Get a public IP on your WAN side.

• Public IP address is your passport to the internet. You couldn't do much without a public IP address. Like post addresses (e.g., 1234 Main Street) are used to deliver mail to your home, a public IP address is the unique IP address assigned to a specific device. This public IP address is used to communicate with the Internet.
• Check the Router's WAN IP and then access www.whatismyip.com, if both of them use the same IP address, the WAN IP is a public IP.

2. Open the ports on the Router.

• VPN Server uses the different ports to communicate.
• If you use the PPTP VPN Server, and you need to open port 1723;

• If you use OpenVPN Server, you need to open the port you set on the NAS, as default, it is port 1194;

• If you use the L2TP VPN Server, and you need to open port 1701, port 500, and port 4500.

• the port forwarding, please kindly refer to this FAQ: https://www.tp-link.com/us/support/faq/1541/

If there is no luck, you can start a new thread with the results above and the model and firmware of your Router.
