Standard Ports Required for SharePoint 2019
When deploying a SharePoint server farm environment, consider individual servers that have specific roles. So, depending on the role each server plays, we may have a different firewall rule and these rules are usually created when we install SharePoint. However, there are some standard ports we should keep in mind.
| Service | TCP Port | UDP Port | Description |
| AppFabric Caching Service (Distributed Cache) | 22233, 22236 | N/A | ICMP Type 0 (ping) |
| People Picker | 53, 88, 135, 137–139, 389, 445, 636, 749, 750, 3268, 3269 | 53, 88, 137–139, 389, 445, 749 | N/A |
| Sandbox Service | 32846 | N/A | This port must be open for outbound connections on all Front-end and Front-end with Distributed Cache servers. This port must be open for inbound connections on Front-end and Front-end with Distributed Cache servers where this service is turned on |

N/A | Ports required for communication between SharePoint servers and service applications (the default is HTTP): |
| SQL Server | 1433 (default) | 1434 (default) | To secure inter-farm communication, we can block the default ports establish custom ports for this communication instead. See Configure SQL Server security for SharePoint Server |
