Remote Assistance

This allows you to check and change your router settings from anywhere on the Internet.

The remote assistance options

There are two modes to choose from:

  • Permanent Mode - Remote Assistance will be switched off on the next reboot
  • Temporary Mode - Remove Assistance will be switched off if it's not used for 20 minutes or after a reboot.

To use remote access, you'd need to browse to the URL (note this change at times if you have a dynamic IP) and enter the Username and Password shown on this page.

To switch the service on click Enable Remote Assistance.


Your router includes a basic firewall. By default the security level is set to Standard mode. This will block incoming connections unless they are defined in Games and Application sharing. All outbound traffic is allowed.

You can change the security level, switch the firewall off or create your own custom security profiles by clicking Configure.

The Firewall options

Dynamic DNS

Dynamic DNS lets you point a fixed domain at your broadband connection when your connection uses a dynamic IP (you would normally need a static IP to do this). You'll need to be signed up to a Dynamic DNS provider such as to use it.

Once you've signed up for a Dynamic DNS service, click the Configure link.

Click the configure link at the top right of the page.

Your Dynamic DNS provider will supply the details you need to use here. Use the Enabled tick box to switch the service on and off as you need it.

Game & Application sharing

This is where you can set up port-forwarding and control UPnP. Current port forwarding rules will be shown under Game or Application near the bottom of the page.

Use the task list at the bottom to edit entries or add new ones.

Game & Application

To set up port forwarding for an application:

  1. Click Create a new game or application at the bottom of the page.

  2. Give your new rule a Name. You can use anything you like but it's generally a good idea to use a name that relates to the program the rule will apply to.

    Make sure Manual Entry of Port Maps is selected and click Next.

    Give your new rule a name and tick Manual Entry of Port Maps
  3. Enter the port and protocol information for your application here and click Add.

    If you need to add further rules you can do so now, otherwise click the Apply button further up the page.

    Enter the port and protocol information here.
  4. Now you'll be back at the Game & Application Sharing menu. The final step is to tell your router which of your connected devices the rule should apply to.

    Click Assign a game or application to a local network device.

  5. Find the new rule you created in the Game or Application drop down box.

    Use the Device box to choose the device this rule will apply to (This box contains a list of the computers that are visible on your network).

    Finally click Add to apply the rule.

    Find the rule you've created in the Game or Application dropdown and click Add.
  6. That's all you need to do, the port forward rule you've created will apply immediately.

Intrusion Detection

The Protected Intrusions table is a log which shows you how many times a number of known intrusion methods have been blocked.

These figures will reset each time you restart your router.

User Management

Each account shown here can log in to your router with their own username and password. By default there'll be one user, named admin.

Here you can change passwords, add or remove users and decide which account is the 'default user'.

Click configure or choose an option from the task list to begin.

The User Management interface.

Content sharing

If your router has a USB port on the side, you can use it to share mass storage devices with computers connected to your network.

Click configure at the top of the screen to set up sharing via NFS, UPnP or FTP.
