# AWS ParallelCluster 在單一私有子網路中，使用 連線 AWS Direct Connect
<a name="network-configuration-v3-single-subnet-direct-connect"></a>

當 [`Scheduling`](Scheduling-v3.md) / [`SlurmQueues`](Scheduling-v3.md#Scheduling-v3-SlurmQueues) / [`Networking`](Scheduling-v3.md#Scheduling-v3-SlurmQueues-Networking) / [`AssignPublicIp`](Scheduling-v3.md#yaml-Scheduling-SlurmQueues-Networking-AssignPublicIp)設定為 時`false`，子網路必須正確設定，才能對所有流量使用 Proxy。頭部和運算節點都需要 Web 存取。
