The following ports must be opened to allow inbound connections.
Lasernet Core 11
Component | Port | Notes |
|---|---|---|
Lasernet service | 3279 / TCP | 3279 is the default port. A Lasernet environment’s service can be configured to use a different port. If multiple Lasernet Core environments are running on the same server, each environment’s service must use a unique port number. Unblock this port only if the Lasernet Core configuration that the environment is running includes a Web Server Input module. In this scenario, an embedded web server listens on the same port as the environment. |
Config Server | 443 / TCP | 443 is the default port. The Config Server can be configured to use a different port. |
Printer Service | 443 / TCP | 443 is the default port. The Lasernet Printer Service can be configured to use a different port. Unblock this port only if the Lasernet Printer Service is running in on-premises mode. |
SQL Server | 1433 / TCP | 1433 is the default port. SQL Server can be configured to use a different port. |
Note
Ensure that Lasernet services, Lasernet Developer, and the Lasernet Printer Service are allowed to establish outbound connections to the Lasernet Config Server. Also ensure that the Lasernet Config Server is allowed to establish an outbound connection to SQL Server.
Additionally, depending on system design, you might need to allow outbound connections from Lasernet services and applications to external services.
