Teamviewer DirectIn - how to allow - configuration in winbox

I would like to use function for direct (faster) connection of two computers with Teamviewer. One PC is at work, second at home. Both have public IP addresses. At home I use Mikrotik (RouterBOARD 433, Router OS v. 2.9), using winbox. I am completely newbie, all my configuration for my home network has been done by my old friend long time ago.

Can someone help me how to allow access to Teamviewer directin function: “Ports 80 and 5938 are used by default for TeamViewer’s DirectIn - feature, which enables faster connection openings by trying to configure a NAT route automatically by using UPnP.”

Thank you in advance.
