  4. Enter the Router address and the Subnet Mask. These will have been provided in the documentation you received from BT.

    If you have purchased 5 public network static IP addresses then your subnet mask will be 255.255.255.248.
    If you have purchased 13 public network static IP addresses then your subnet mask will be 255.255.255.240.

    If you want to open the firewall put a tick in Auto Firewall Open. This will open the WAN side of the firewall.
    Click Save and enter the router password if required. The default password is the s/n number on the Business Hub. When the settings are saved a message will appear to confirm the change.
