Unable to connect to network device

Hello,
I have setup my brand new RB2011 router and most of what I need seems to be working fine. The only issue I have run into is that I am not able to map to the shared drive on my NAS (192.168.55.10) from my Win 10 PC (192.168.55.4). I am able to log into the NAS web interface by using its IP, but the device fails to show up on my PC network. I have not changed any of the default firewall rules or the routes that came pre-configured with the OS. What am I missing?

Appreciate your time and help.

Pete

Put both devices into same hardware switch. You could have some problems with bridging…
