Port Restrictions
By default, when access to a Resource is granted, all ports on that Resource are accessible. However, you can restrict access to specific ports on a Resource by defining port restrictions. When port restrictions are defined, only the specified ports will be accessible to users, roles, or machines that have access to the Resource. To specify specific ports, enter either a single port (e.g.,80), a comma-separated list of ports (e.g., 80,443,8080), or a port range using a hyphen (e.g., 8000-8100).
