Enable Internet Access for WorkSpaces Pools
After your NAT gateway is available on a VPC, you can enable internet access for your WorkSpaces Pools. You can enable internet access when you create the WorkSpaces Pool directory. Choose the VPC with a NAT gateway when you create the directory. Then select a private subnet for Subnet 1 and, optionally, another private subnet for Subnet 2. If you don't already have a private subnet in your VPC, you may need to create a second private subnet.
You can test your internet connectivity by starting your WorkSpaces Pool, and then connecting to a WorkSpace in the pool and browsing to the internet.
