# Port Requirements

For the WorkSpaces Manager Appliance to function properly, the following ports must be accessible:

<table><thead><tr><th width="334">Service</th><th>Port</th></tr></thead><tbody><tr><td>AWS APIs</td><td>TCP/443</td></tr><tr><td>RDS MS-SQL</td><td>TCP/1433</td></tr><tr><td>nuvens.info</td><td>TCP/443</td></tr><tr><td>DNS</td><td>TCP/UDP 53</td></tr><tr><td>RDP</td><td>TCP/3389</td></tr><tr><td>Active Directory</td><td>TCP/UDP 88 (Kerberos authentication)</td></tr><tr><td>Active Directory</td><td>TCP/UDP 389 (LDAP) or TCP/UDP 686 (LDAPS)</td></tr><tr><td>Active Directory Global Catalogue</td><td>TCP/3268</td></tr><tr><td>Active Directory and Samba</td><td>TCP/UDP 445</td></tr><tr><td>NetBIOS</td><td>TCP/UDP 135 &#x26; TCP/UDP 138</td></tr><tr><td>NTP</td><td>UDP/123</td></tr><tr><td>NNTP</td><td>TCP/433</td></tr></tbody></table>

When WorkSpaces Manager is configured to display user location using Amazon CloudWatch Log Groups together with an Amazon EventBridge rule that detects the client IP address, the following URLs must also be added:

| Service                       | Port    |
| ----------------------------- | ------- |
| <https://maps.google.com>     | TCP/443 |
| <https://maps.googleapis.com> | TCP/443 |
| <http://ip-api.com/json>      | TCP/80  |

The image below illustrates an example of a user’s location derived from their IP address and displayed in Google Maps:
