BT Blocked Ports

In order for us to maintain a high level of service and protect our network against potential attacks we're currently making a change to our network.

As a result we will be blocking all incoming traffic to ports that we believe susceptible to attack for some of your end users, these include 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 customers firewall however in the event of a compromised router the ports may be unblocked. We will block the ports at a network level to ensure security.

It is unlikely customers need these inbound ports open and customers should be able to continue to use their services as normal.
