QNAP-DLNA server in different VLANs

English Networking
1

Hi,
I’m currently reorganizing my home-LAN and trying to separate devices into diffent VLANs (office, media,…).
As I know that auto-discovery over inter-vlan-borders are a pain, my plan is to use one NIC of my TS-453D for “normal” NAS-purposes (fileserver,…) on office VLAN and connect the second NIC to media vlan.
That works nicely, my very “sensitive” LG-Smart-TV does instantly recognize the DLNA-Server on the QNAP.
Disadvantage is, that NIC2 is exposed to media-device traffic.
As the QuFirewall app (nas fw 2.5.8, qufirewall ver 2.5.0) does not support port-based rules I do not see any way to limit the communication. My router (Unifi ucg ultra) also does not help, because communication within media vlan will not be limited by the firewall.
I would be grateful for suggestions how to solve that issue.

I haven’t used DLNA in many years as I switched to Plex and jellyfin.

Have you tried service binding ?

DLNA is considered obsolete and I don’t know how much QNAP is supporting it any more. So I would move away from using DLNA and start using Plex. A far better user experience.

If NIC1 is on the office on “VLAN 1” and NIC2 is on the media LAN or “VLAN 2” then yeah, NIC2 will be exposed to media traffic.

Firewall rules are not how you limit or route VLAN traffic. So yeah you don’t do it that way.

As @dolbyman said, use service binding on to tie the specific services to each NIC. That way, it forces the QNAP to use specific NICs for specific purposes.

Thanks for suggesting service binding, thats exactly what I was looking for.

I was sticking with DLNA because it’s natively supported by my LG-Smart-TV.
Additonally I’m using the TV not only for videos but also for viewing photo-collections which DLNA does support and plex (as far as i know) does not.
which service would you recommend for that purpose?

And regarding service binding: which services are needed for the media streaming purpose? It seems that the nas requires a restart after changing service binding. So doing trial and error is quite tedious.

I use Plex for photo viewing, works just fine

There is even a dedicated app (Never used it myself)

Also what LG TV do you use ? I have a LG 77G3 and Plex is offered as an app (same with jellyfin)

My LG is a LG55C7V. I’ve checked: your are right, there is a plex app. I will check this option.

Regarding the suggestion of using service binding:
I’ve activated this feature and deactivated all available options for NIC2. It still works (which means the LG-TV will immediately find the DLNA-server on the NAS and streaming works ok)

Thanks for that idea!

Hi @TimTom ,

Thank you for choosing QNAP.

If we understand correctly, you would like to have your media available across different VLANs for your TV setup.

For your reference, you may also consider Plex as an alternative option. Please see the following official QNAP FAQ:

Thank you.
