Cannot access the Synology NAS on the LAN until I press the power button on the NAS

Cannot access the Synology NAS on the LAN until I press the power button on the NAS.

 

I have been having issues with the Synology NAS since switching from DD-WRT to Sophos UTM 9. Sometimes I cannot access it from the LAN via a PC. I have configured and reinstalled it a couple of times to try to get the NAS to work correctly.

 

I installed the current version of the UTM on QOTOM-Q19G4-S02. I have the Firewall, DNS, DHCP and Wireless Protection configured.

 

 

The NAS is an ioSafe DS214 running the current version: DSM 6.1-15047 Update 2 (2017/03/21)

 

The IP Address is 192.168.1.149

 

Last night it was working fine:

 

1) I could ping the NAS by its IP address using the PC

 

2) Access the share folder via Windows Explorer on the PC using Network > NAS (\\NAS)

 

3) Log on to the WebAdmin page using the PC

 

4) I can ping the NAS by its IP address using the an iPhone

 

5) Access the NAS using the DS File App on the iPhone

 

6) Access the NAS using the DS Photo App on the iPhone

Do you think it is the UTM that is blocking access to the NAS from the LAN?

 

What logs should I be looking into on the UTM that might explain why I am loosing access to the NAS?
