7. Para Protocol and Ports select option TCP e Special Local Ports. eu uso 2 ports for SCCM deployment (8080, 14331) and also added standard SQL TCP ports (1433,1434,4022). After entering ports click Próximo;

8. Para Action (in this case leave by default Allow the connection). Clique Próximo;

9. Para Profile, Saia por padrão, clique Próximo;

10. Enter a name for your rule (for example SQL TCP Ports), so you can easily find it in the future. Clique Terminar;
