Hello everyone,
I am reaching out and ask for your help in solving a big issue.
In a visual radio studio we have:
- 6 PTZ cameras running HX3 NDI outputs on a dedicated NDI network VLAN
- one main vMix PC doing the 16/9 video production
- a secondary vMix set for vertical 9/16 production
- one playout PC that runs video files on NDI output
- all Audio is on AoIP Axia Live wire, on a separate VLAN
All the PCs each have 3 network cards,connected one in the NDI VLAN, one in Axia VLAN and one in the LAN/internet enabled VLAN.

On all the PCs we have installed NDI tools and indicated in the NDI Network Manager the use of the dedicated network card they is connected in the NDI VLAN.

We have also set the metric on the NDI cards to 1, as we have found some advices, and set permanent route for the NDI trafic on that specific network card.

But even we have done all that, each time we enable in vMix one or more NDI outputs, those streams end up being broadcasted through the LAN network card instead of the dedicated NDI card.

And the result is that the PGM from vMix PC1 is not properly "seen" or received on the second vMix PC2, and vice-versa.

So my question is: is there a specific procedure that could indicate to vMix what network interface to use for the NDI trafic and not push it into the same network interface that he is using for internet streaming?

I am looking forward to any advice you may have.
Thank you.
