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.
Link Checking:
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.
