# AWS ParallelCluster 在使用连接的单个私有子网中 AWS Direct Connect
<a name="network-configuration-v3-single-subnet-direct-connect"></a>

当 [`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) 设置为 `false` 时，必须正确设置子网以便对所有流量使用代理。头节点和计算节点都需要 Web 访问权限。
