Inbound Connections

In order for users to browse to the Cascade CMS environment, one or more of the following ports must be open on the application server:

HTTP/HTTPS: 8080, 8443, 80, 443

NOTE: The ports listed above are the most common, but you can configure Cascade CMS to run on a custom port if needed. See this page for more information.

Outbound Connections

The sections below outline the default ports that Cascade CMS will use for corresponding outbound connections.

Authentication:

LDAP/LDAPS: 389, 636

Database:

MySQL: 3306

SQL Server: 1433

Oracle: 1521

Publishing:

SFTP Transports: 22

FTP/FTPS Transports: 21, 990

MySQL Database Transport: 3306

Email:

SMTP Mail Server: 25

NOTE: As of Cascade CMS 8.13+, system-generated emails will be sent via an external service (Sendgrid). If you are not receiving emails from within the application, you may need to whitelist *.sendgrid.com at your email server to allow for deliveries. These emails will come from noreply@cascadecms.com. If you are using a proxy, Cascade CMS 8.16+ allows for configuring outbound connections for email as described here.

External Link Check: 80, 443*

Connectors:

Google Analytics Connector**: 80

Twitter Connector**: 80

Wordpress Connector**: 80

*Since end users can link to any URL and port, the external link check could require other outbound ports for specific URLs. In general, you should be ok with only allowing port 80 and port 443.

**Only necessary if using the Google Analytics Connector, WordPress Connector, or Twitter Connector.
