When configuring a multi-NIC virtual machine (VM), it is essential to ensure that at least one NIC is connected to an external network. This is crucial for proper traffic flow, especially when the VM needs to communicate with devices outside its local environment or virtual network. The external network connection allows the VM to access the internet, communicate with other networks, and participate in broader network functions, which are essential for many applications.

Connecting to an external network through one of the NICs enables the VM to receive traffic from and send traffic to outside sources. This function is pivotal in production environments where VMs require interaction with users, services, and resources beyond their internal networks.

In contrast, having both NICs attached to the same VLAN does not guarantee that the VM has access to external resources or communication capabilities. The presence of NICs from different manufacturers or the limitation of assigning only one IP does not contribute to achieving efficient traffic flow or connectivity with external networks. Thus, ensuring that at least one NIC is on an external network is a fundamental requirement in a multi-NIC VM configuration.
