Ports for file gateways
The following illustration shows the ports to open for a file gateway.
Note
For specific port requirements (including NFS and SMB port requirements), see Port
Requirements (p. 386).
You only need to use Microsoft Active Directory when you want to allow domain users to access an
Server Message Block (SMB) file share. You can join your file gateway to any valid Microsoft Windows
domain (resolvable by DNS).
You can also use the AWS Directory Service to create an AWS-managed Microsoft Active Directory in the
AWS Cloud. For most AWS-managed Active Directory deployments, you need to configure the Dynamic
Host Configuration Protocol (DHCP) service for your VPC. For more information about how to create a
DHCP options set, see here.
In addition to the common ports, file gateways require the following ports.
