Allow PING

The Internet Protocol (IP) supports more than just TCP and UDP traffic; it can also carry ICMP messages. By default, all ICMP requests are closed on your instances. However, adding an ECHO REPLY ICMP traffic rule to your security group allows you to ping your instance. Enabling PING makes it easier to integrate with your preferred monitoring tool or service.

To enable ingress ping connectivity to your instance, follow these steps:

  1. Choose the Security Group
    Navigate to the instance list in the Portal and select the security group associated with your instance to which you want to add ping traffic. Note that enabling ping will also apply to all instances attached to this security group.

  2. Add a Rule
    Within the selected security group, create an INGRESS rule. Be sure to restrict the source IP or network range, and select the ICMP protocol.

  3. Configure Echo
    Set the type to ECHO (type 8) and the code to NO CODE.

  4. Save
    Click ADD to save your rule. Please allow some time for the rule to propagate.
