ASE uses default ports as defined in the table below. If any ports configured in ase.conf file is unavailable, ASE will not start.

Port Number Usage
80 Data port for HTTP and WebSocket connections. Accessible from any client (not secure). If you are installing ASE as a non-root user, choose a port that is greater than or equal to 1024.
443 Data port for HTTPS and Secure WebSocket (wss) connections. Accessible from any client. If you are installing ASE as a non-root user, choose a port that is greater than or equal to 1024.
8010 Management port used by CLI and REST API for managing ASE. Accessible from management systems and administrators
8020 Cluster port used by ASE for cluster communication. Accessible from all cluster nodes.
8080, 9090 ABS ports used by ASE for outbound connections to ABS for sending access logs and receive client identifiers of suspected attacks.

Important: The management ports 8010 and 8020 should not be exposed to the Internet. If you are setting up the deployment in an AWS environment with security groups, use private IPs for ASE to ABS connections to avoid security group issues.
