How to set up port forwarding

How to set up port forwarding


Our hubs have a built-in firewall to prevent unauthorised external access to devices that are connected to the internet. To allow external access for things, like online games or hosting of an FTP server, some software or applications might need to reconfigure the firewall. You can do this with Port Forwarding.


The following steps are applicable for all Sky Hubs up to Hub 4



Here are the steps:


  1. Open a new web browser window and delete the contents of the address bar.

  2. Type into the address bar and press Enter. You'll see the Sky Hub Menu.

  3. Click the Advanced tab and enter the username and password.


  • Default username: admin
  • Default password: sky
  • Default Password for Hub 4/ Sky Broadband Hub: The default WiFi password printed on the hub
  • If these have been changed, enter the current username and password.


  1. Click LAN IP Setup then Add under Address reservation.

  2. Select the radio button next to the device the traffic should be forwarded to, and take note of the IP address.

  3. Click Add. The Hub might request a restart. Click OK and allow it to restart before continuing.

  4. Log back into the Hub if you need to. Go to Security, then click Services and Add Service.

  5. Type a Name (something you'll recognise, like 'PS4' or 'Xbox').

  6. Choose the type or port (TCP / UDP or both).

  7. Type the Start and Finish port.

  8. Click Apply. If you see 'service name is already present in the existing firewall or custom services,' click OK.


If you have more than one port number / range (PS4 usually uses 4 numbers / ranges), repeat steps 8-11.


  1. Repeat from step 8 until you've added all port numbers/ranges, then continue.

  2. Click the Firewall Rules.

  3. Click Add under Inbound Services.


fill in the IPv4 settings.


  1. Choose the name you set up from the Service drop-down.

  2. Choose ALLOW always from the Action dropdown.

  3. Next to Destination IPv4 LAN address, type the IP address you noted earlier.

  4. Click Apply to save your changes. If you added more than one port number/range go back to step 14 until you've added them all.

I’m having problems port forwarding – what should I do?


If you’re experiencing difficulties, make sure that you've checked:


  • All of the ports you need are forwarded.

  • The right protocol is in use.

  • Any other active firewalls on your home PC (such as McAfee, Norton or Windows Firewall) may also need port forwarding set up.

Adding a new port forwarding rule may prevent the hub from working properly. If this happens:


  1. Disable the new rule by unticking Enable.

  2. Select the radio button next to the rule then click Delete.

  3. Reset your hub by holding the Reset button on the back of the Sky Hub for 30 seconds, until the power light flashes.


Resetting will revert the Hub back to its default settings, removing all changes. Any Hub settings you’ve changed will be reset, including your WiFi password and name.
