Personally I wouldn't recommend doing this unless you have enabled encryption with a secure certificate.
By forwarding the ports you are opening an attack vector to your miners with a very common protocol (VNC).
Also, port forwarding is only getting you to one miner. If you have multiple you would have to then jump from that box to another.
You can use TeamViewer for free with the personal use license. I access my miner consoles from my phone to adjust things, it works great.
Yeah I was worried that something like this can be a possibility Did a little research and decided to go with Teamviewer. Thanks for answer man!
