Router Configuration

If your DiskStation device is on a local area network, other devices on the Internet cannot connect to it. You can set up port forwarding rules at Control Panel > External Access > Router Configuration to make your DiskStation device accessible over the Internet.

Setting up Router

Before adding port forwarding rules, you need to set up a connection between your DiskStation device and the router.

Note:

  1. To configure port forwarding rules and assign static IP address, you need to have administrative privileges to the router.
  2. Before setting up DiskStation device's connection to an UPnP router, make sure DSM has successfully retrieved the external IP address of your DiskStation (at Control Panel > External Access > DDNS). If not, please check the network and firewall settings of your DiskStation device and the UPnP router.

To set up DiskStation device's connection to your router:

  1. Click Set up router to launch the setup wizard. DSM will begin by testing the following network components/settings before proceeding to the next step.
  2. Depending on the type of your router, do one of the following:
  3. If you are required to manually set up DiskStation device's connection to the router, do the following:
    1. Choose your router from the Router drop-down menu.
    2. Note:

      If you cannot find your router here, click Update List to get the latest list from Synology.

    3. Set up protocol and port of your router. The protocol and port vary depending on the model of your router. If you cannot connect using the default Protocol (HTTP) and Port (80), refer to the documentation that comes with your router for correct settings.
    4. If your router requires a custom account, tick Use custom account and fill in the Account and Password fields.
    5. Click Apply to finish.

Managing Port Forwarding Rules

Port forwarding rules can specify destination ports of your DiskStation that will receive packages from specific ports of your router.

If your DiskStation connects to the Internet via a router, please click Create to open the port forwarding setup wizard.

There are two ways to add port forwarding rules:

You can use the following syntax to specify port numbers and range:

Note:

To save rules:

Click Save after creating the rules. Otherwise, the rules won't be applied.

After saving the rules, you might need to wait for a few minutes before the rules start working, depending on the models of your routers.

To test whether your rules are working or not:

Choose the rules you want to test and click Test Connection. The result will be displayed in the Connection Test Result column.

For Wireless Router Configurations*

When your DiskStation acts as a wireless router, port forwarding rules will be carried out directly by DiskStation.

To add port forwarding rules:

  1. Click Create to open the setup window.

  2. Specify the Service name, Protocol (TCP or UDP), Private IP Address, Private Port and Public Port. You can use the following syntax to specify port numbers and range:
  3. Click Create at the bottom to complete the settings.

Note:

Most routers permit local machine ports and router ports to be different when configuring port forwarding rules. If your router supports this feature:

DMZ*

You can enable DMZ on your DiskStation when the Network Map Configuration is Wireless Router. A host in the DMZ can connect directly to the external network, free from limitation and protection of the firewall. It is usually used for setting up servers.

To enable DMZ:

  1. Click DMZ Settings to open the setup window.
  2. Tick the Enable DMZ checkbox.
  3. Enter your DMZ Host IP address.
  4. Click Apply.

Note:

From the external network, you will need an external IP address retrieved by DiskStation to connect to a host in the DMZ.
