Connect to mysql remotely

[mrapache]

I have two VM's running inside an ESXI host machine

IP 10.0.1.10 runs Win 2016 server with XAMPP just fine.
IP 10.0.1.11 runs CentOS with LAMP and that runs fine.

When I want to connect remotely thru cli to a mysql db to .10 from .11 that works fine.
However when I try to do the reverse which is what I want namely to remotely connect to a .10 mysql db
from .11 I cannot connect.

Port forwarding is allowed for 3306 for the .11 address.

I have no bind-address set for .11in my.cnf file as that didn't work, nor for like localhost, or 0.0.0.0.

Any help would be most appreciated!!!

I'm thinking Server 2016 might have firewall. How does it not connect? Error message? Log?
