You're looking to set up a multi-NIC network card on your ITX computer for better performance and isolation between services like game servers and Plex. This can help reduce conflicts and improve speed. It's a bit technical, but here are some key points to consider:

- You'll need to install the appropriate drivers for your specific NIC model.
- Ensure your router supports multiple NICs and has enough bandwidth for this setup.
- You may want to configure VLANs or QoS settings if you're using advanced networking features.
- If you're not comfortable with these steps, consider consulting a tech-savvy friend or seeking professional help.

Let me know if you need help finding the right drivers or configuring your router!

Are you inquiring about physically splitting a slot for a NIC connection or about directing network services through one port instead of another? Unless you're maximizing the speed of a single interface, this approach won't deliver meaningful results. You might notice brief latency reductions, but consistency won't be achieved.

Reducing latency is crucial for me because using frostwalker on a Minecraft server can significantly impact other services. This discussion focuses on directing services to particular network interfaces rather than changing the PCI slot configuration.

The setup works well for a single nic without problems. I tested it extensively on one nic and didn’t encounter any issues. What operating system are you using? How much data are you transferring through your nic?

The general agreement is clear. I’m wondering how to proceed at this stage. I’m using the newest Ubuntu release. I’m uncertain about the available bandwidth, but I might start a tracker.

Typically, services offer an easy option to specify the interface and/or IP address they should connect to, such as configuring the ListenAddress in /etc/ssh/sshd. You should review each service's manual page to understand how to set it for a particular interface or IP. Also, note that most services connect to all available interfaces by default; if a service isn't responding or is slow across all interfaces, the problem is likely related to CPU usage rather than network bandwidth.
