Verifying port-level network connections

To ensure that access between the StorageGRID Appliance Installer and other nodes is not obstructed by firewalls, confirm that the StorageGRID Appliance Installer can connect to a specific TCP port or set of ports at the specified IP address or range of addresses.

1. From the menu bar of the StorageGRID Appliance Installer, click Configure Networking > Port Connectivity Test (nmap).
   The Port Connectivity Test page appears.
2. From the Network drop-down box, select the network you want to test: Grid, Admin, or Client.
3. Specify a range of IPv4 addresses for the hosts on that network.
   For example, you might want to ping the gateway on the network or the primary Admin Node.

   Specify a range using a hyphen, as shown in the example.

4. Enter a TCP port number, a list of ports separated by commas, or a range of ports.
   
   
   
5. Click Test Connectivity.
   If the port-level network connection is valid, the "Port connectivity test passed" message appears, with the nmap command output listed.
