# 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 |

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

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nuvens.cloud/install/installation-prerequisites/port-requirements.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
