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

Aaron Windsor

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

 

 


 

When it is not working:

I cannot ping the NAS from the PC or iPhone

 

NAS:

Power light is on and static, Disk one and two are on green (static and sometimes Blinking. The LAN is blinking Green (Network is active) The Status is green and Static (Volume Normal).

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?

    Hi, Aaron, and welcome to the UTM Community!

    Is the NAS inside the same Ethernet segment as the device you're using to access it?  If so, why do you think the traffic goes through the UTM?

    You've already tried part of #1 in Rulz, but you should try the other parts, too.

    Cheers - Bob

    Hey Aaron.

    I don't think UTM has nothing to do with this. Your PC and the NAS are on the same network, which I'm assuming by your screenshots to be 192.168.1.0/24. Local communication does not go through the UTM.

    I did notice you are obtaining the NAS IP address trough DHCP. I would first setup a static IP address on this device outside of your DHCP range (that appears to be 192.168.1.100-150), as your device might be having some issue keeping its IP address. Set it to 192.168.1.151, for example, or any other available IP that is not between 192.168.1.100-150 and see if anything changes.

    But, to me, it honestly seems that the issue is on your NAS.

    Regards,

    Giovani
