In order to us to maintain a high level of service, and protect our network against potential attacks, we need to make a change which affects your account.
This change is related to the broadband firewall which all of our customer accounts have access to.
We'll be making a change to block incoming traffic on ports 53, 111, 135, 137, 138, 139, 445, 515, 1080, 1433, 3128, 3306, 6000.
In most cases these ports will already be blocked by your local firewall however in the event of a compromised router, the ports may be unblocked or used in a potential attack.
It is unlikely you will need these inbound ports open, if you do you please visit http://contactus.plus.net and let us know by responding to this support ticket.
There's nothing you need to do, and your connection should continue to work as normal apart from a brief disconnection whilst we make these changes. In the vast majority of cases your router will automatically reconnect. If you experience problems getting reconnected following this maintenance please try a single reboot of your router.
