Frequently Asked Questions
Find quick answers about VPC Peering on FPT Cloud, from how it works to fixing approval problems and Failed connections.
What is VPC Peering?
VPC Peering connects two or more VPCs over a private internal network. Resources communicate directly, as if they were on one network, without crossing the internet. You get strong security, low latency and stable performance.
How does VPC Peering work?
It creates a private connection between VPCs. After the connection is established and the Route Tables are configured, traffic is routed over the peering link.
What is VPC Peering used for?
It lets VPCs share resources and transfer data securely. Typical uses are connecting application environments, databases and internal services across multiple VPCs.
The two VPCs still cannot ping each other. What should I check?
Check the Route Table, the Security Group and Firewall rules, and the status of the connection. Make sure the CIDR ranges do not overlap and that the VM or Instance allows ICMP or the traffic you need.
How do I check whether I can use the service?
FPT Cloud enables the service per VPC. If you do not have access, the Portal shows that the service is not enabled. Contact FPT Cloud to enable it.
Why is my connection in the Pending acceptance status?
Either your account does not have the Accept permission on the VPC Accepter, or the two VPCs are in different Tenants or Regions. A user with the Accept permission on the VPC Accepter must accept within 7 days. See How VPC Peering approval works.
Why can I see a request but not click Accept or Reject?
Your account may lack the VPCPeering:Accept permission on the VPC Accepter, or the VPC Gateway on the Accepter side is not Active and Online. Ask your organization's IAM administrator to grant the permission.
What do I do with a Failed connection?
Click Delete so the system releases the remaining resources, then create the connection again. If the error repeats, contact Support. See Handle a Failed connection.
