Why Can't I Ping My EIP After It Is Bound to a GaussDB Instance?

1. Log in to the management console.
2. Click in the upper left corner and select a region and project.

3. Click in the upper left corner of the page and choose Databases > GaussDB.
4. On the Instances page, click the name of the target instance to go to the Basic Information page.
5. In the Connection Information area, click the security group name in the Security Group field.
6. Check whether the ECS NIC security group allows the inbound ICMP traffic.

   Table 1 Security group rules

   Direction	Type	Protocol/Port Range	Source IP Address
   Inbound	IPv4	Any/Any	0.0.0.0/0 0.0.0.0/0 indicates all IP addresses.
   Inbound	IPv4	ICMP/Any	0.0.0.0/0 0.0.0.0/0 indicates all IP addresses.

If the affected EIP can be pinged from another ECS in the same region, the virtual network is functional. In such a case, submit a service ticket to contact technical support.
