This is the port used by Plusnet/BT to update your firmware. There's been a lot of discussion about this in the past. I don't think it can be closed. See also. https://community.plus.net/t5/My-Router/IP-TCP-4567/m-p/1535448#M6334

If you can't live with it then I fear that you will have to buy your own third party router.
