I soon bought a Mikrotik Routerboard R750r2 hEX Lite, when I started to configure I could not connect to the internet through the browser, if I tried the ping or traceroute the communication was done. I was configuring on Windows PC.
By chance I tested the connection on a linux computer and it was perfect. The browser is working, ping is working and so on.
So I connected again to a Windows computer and the browser did not work, but the ping did.
I did a complete reset on Mikrotik and started to configure, but the same problem happened, computer with Windows without browsing and Linux can.

Its current version is v6.38.1 with firmware 3.33.

Use an ADSL modem and a dedicated link, the problem appeared in ADSL. DHCP is distributed through an AD on the local network.

Port 1 is with DHCP client for ADSL
Port 2 is dedicated link IP omitted.
Port 3 is with the local network.

Current setting after reset below:

interface ethernet
set [ find default-name=ether1 ] name=P1_VivoADSL #ADSL
set [ find default-name=ether2 ] name=P2_VivoDEDICADO #DEDICATED
