AOA Everyone, I am config. a VPC Peering connection. I have

  • 2 VPCs
  • 3 Subnets
  • 3 VMs

VPC-one has 2 Subnet associated (i.e. subnet-one & subnet-two) VPC-two has 1 Subnet associated (i.e. subnet-one) Each VM is connected to each Subnet

  1. srvone (of subnet-one of VPC-one)
  2. srvtwo (of subnet-two of VPC-one)
  3. srvthree (of subnet-one of VPC-two)

So the problem I am facing is that the VMs in VPC-one are successfully communicating i.e. Ping. But any VM from VPC-one is not ping to VM in VPC-two.

VPC-one route-table

VPC-two route-table

VPCone-to-VPCtwo Peering Connection

VPCone-subnetone Security Group (Inbound) Rules

VPCone-subnettwo Security Group (Inbound) Rules

VPCtwo-subnetone Security Group (Inbound) Rules

VPCone-subnetone Security Group (Outbound) Rules

VPCone-subnettwo Security Group (Outbound) Rules

[VPCtwo-subnetone Security Group (Outbound) Rules][9]

VPCtwo-subnetone Security Group (Outbound) Rules is same as VPCone-subnetone SG (I don't have permission to add more than 8 links or add images)

  • "not ping to VM in VPC-two" - what's happening? A timeout, some connection refuse errors? How do you test that? Only pinging does not work? What about ssh? – Marcin Sep 10 '22 at 10:53
  • I have only Allowed ICMP at ACL level. want to ping two VMs at two different VPCs. – abdul rehman Sep 12 '22 at 17:59
