MOBO and NDI both offer dual Ethernet ports.
Hello, I'm not sure where to share this post, so I'll try here. I'm setting up a stream using a dual PC setup with NDI instead of a capture card. The motherboards have two Ethernet ports—one at 1Gbps and another at 2.5Gbps. My question is, can I connect my two computers through the 1Gbps port to bypass the switch/router, while still using the 2.5Gbps port normally for the router?
Yes, it's possible. Using a standard Ethernet cable with pre-applied connectors works fine. Gigabit cards typically recognize the wire order and function correctly. The two network cards linked together won't get IP addresses automatically; you'll need to assign them manually, ideally using private IP ranges not assigned by your router. These private classes include: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. If your router assigns an IP like 192.168.1.2, you can set the network cards to 10.0.0.1 and 10.0.0.2 with a subnet mask of 255.255.255.0. Also remember, your router must have a 2.5G Ethernet port to support speeds up to 2.5Gbps; otherwise, it will only reach 1Gbps.
You aim to achieve specific results by using this configuration.
Ensure high frame rates are supported on your primary machine and record the footage using the secondary device directly, avoiding router transmission of NDI data.
