QNAP HS251+ Virtual Swich

Hi,

I’ve installed Roon on the Qnap HS251+, and it seems to work fine.
My Qnap HS251+ uses only SSD disks so it is completely silent.
To reduce network traffic I want the storage and Roon core in one BOX.
The box can sit in the hifi rack and benefit from the power filters for clean current.
It works fine, but… I do not want an extra switch in the system.
The Qnap has two Ethernet adapters. Adapter one is connected to the router.
Adapter two is not used.
Using the new virtual switch I want to use the second adapter to connect to the
End point. (for the time being a Meridian MS600).
I was able to define the switch, but Roon no longer sees the MS600.
Then I messed up the complete Network configuration, and had to use the hardware reset.
It is probably a routing issue, or perhaps what I’m trying to do isn’t even possible.
Any help is much appreciated. “@support

Hi @Dirk_Thys,

Are other networked endpoints showing up okay? Is it only the Meridian device that isn’t seen?

Hi Dylan,
I have but one endpoint, except of course my iPhone.
If I plug my computer in the ethernet port, It works fine.
When I plug in the meridian it is not found.
I think because the Meridian gets a IP Address in a other range.
Unfortunately my knowledge of Network is not that great.

Dirk.

Why not connect the meridian to the router as well. Not sure how well the qnaps work as a physical layer 2 switch at all its designed to route vms on the nas not actual hardware. In you image both ports are assigned the same IP so that wont work at all. I dont think the VS should be running on both ports its usual to have it assigned to just one of them. The QNAP will bridge internally to it as far as I understand. Which method did you use to set it up.

Hi,

I want to keep the music data stream from the network.
The Qnap can sit in the hifi rack and benefit from the clean power.
I have but one ethernet connection in the music room, and don’t want a switch in the system.
By using the second ethernet port, the data can remain in the Qnap.
A direct short quality cable can run between the NAS and the End-Point.
(In my case a Meridian M600).
After Upgrading the Qnap to the last available 4.6.3 release;
I can’t get the Sooloos system up again. Not happy about that!
So after some experimenting, I got the configuration working.
The virtual switch is defined to use both ports.
Both Adaptors get the same IP address as does the virtual switch.
(I do find this a bit strange, but I can’t change it. The Qnap configures it that way.)
Obviously this didn’t work.
I found out that the Meridian got a IP-address in a completely different Range.
To my understanding this is because the second Ethernet Adaptor doesn’t see the DNS server.
So I dove in the configuration of the MS600 and defined a static IP address.
The Ip address is within the range of the DHCP server and said to be unused by the provider.
I also defined the default gateway, both DNS servers and the network mask.
After these changes it works!
Can’t exactly tell what happens inside the QNAP, I think it works as a bridge now.
Believe it or not, it does make a difference to the sound.
Then I started to copy my music to the NAS and by doing that, I ruined the hole thing.
Last night I did a complete reconfiguration of the NAS, reinstalled Roon and carefully copied part of my music files.
Happily everything is working fine again.
I will have to expand to larger SSD disks though.
So finaly I can start playing around with Roon!

Regards,
Dirk
