Deep Security 11.1 has reached end of support. Use the version selector (above) to see more recent versions of the Help Center.
Port numbers
If connecting Deep Security Manager, Relay, or Agents through a:
- firewall or AWS/Azure/NSX Security Group
- router
- proxy
- other network address translation (NAT) device
you'll need to know the required domain names or IP addresses, ports, and protocols.
Firewall policies, proxies, and port forwarding often require this information. This is especially true for connections to services on the Internet, such as DNS, time servers, the Trend Micro Active Update servers, Trend Micro Smart Protection Network, and Deep Security as a Service. If a computer has other installed software that listens on the same ports, you must resolve the port conflict.
Default port numbers are in these tables. If the default port numbers don't work with your network or installation, you have a proxy, or if you require SSL or TLS secured versions of the traffic, the tables indicate if you can configure it.

If your Deep Security Manager runs inside the Azure cloud boundary, it uses a direct route to interact with the Azure SQL Database server. For more information, see https://docs.microsoft.com/en-us/azure/sql-database/sql-database-develop-direct-route-ports-adonet-v12. This is only required when using Azure SQL Database with Deep Security Manager deployed on Azure, for example, the Deep Security Manager VM for Azure Marketplace. |

| TCP | 4123 | Localhost Relay |
Communication of Agent to its own integrated Relay. This port should not be listening to connections from other computers, and you don't need to configure it in network firewall policies. But if you have a host firewall on the Deep Security Manager server itself, verify that it does not block this connection to itself. Also verify that other applications do not use the same port (a port conflict). |

Note: In Deep Security Agent 10.0 GM and earlier, agents didn't have support for connections through a proxy to relays. You must either:
- update agents' software (see Get Deep Security Agent software), then configure the proxy (see Connect agents behind a proxy.)
- bypass the proxy
- change the application control rulesets relay setting as a workaround
