How to Restrict Access to Specific Port(s) and Allow ICMP to a Backend Resource
Resolution
This article describes a scenario in which an administrator needs to allow access to a backend server through just certain ports; the administrator also needs to allow ICMP to that host. In the following procedure, port 443 and ICMP will be allowed to a specific host by creating two access control rules.
Procedure:
- Log in to AMC.
- Click Access Control in the main navigation menu.
- From the list of the rules, select an existing rule or use the New button to create a new rule.
- In the From field select a user or group that should be granted access to the resource.
- In the To field select the backend resource, resources, or resource group, and then click Next to go to the Advanced section.
- In the Advanced section under Access method restrictions, restrict the Protocols to ICMP:
- Click Finish to save the rule.
- Create a second rule that allows your users or groups to connect to the same resource, resources, or resource group: under the Advanced section of the rule, restrict the Protocols to TCP and enter port 443 (you can also specify multiple ports) as shown in the following screenshots:
