Known Issues

VPC Resource Limitations VPC resources are limited. For more information, go to Amazon VPC Limits in the Amazon Virtual Private Cloud User Guide.
CC1 instances CC1 instances are not supported for use in a VPC.
VPC Dashboard filtered view If you have created more than one VPC and choose to filter the VPC dashboard view to only view a single VPC, the resource counts for security groups, Internet gateways, virtual private gateways, customer gateways, and VPN connections reflect all VPCs.
Older API Version Clients and Latest Console Display Different Results If you use a client that is based on an older API version of Amazon VPC (earlier than version 2011-01-01), but you also use the AWS Management Console to manage your VPC resources, you'll see different results between the two interfaces.
Elastic IP Addresses Not Interchangeable Any EC2 Elastic IP addresses your AWS account has cannot be used with your VPC, and any VPC Elastic IP addresses you have can't be used with EC2.
Security Groups Not Interchangeable Any EC2 security groups your AWS account has cannot be used with your VPC, and any VPC security groups you have can't be used with EC2.
Traffic Sent to Overlapping IP Address Ranges Is Dropped For customers using the optional IPsec VPN gateway: If your VPC's IP address range overlaps with an IP address range in use within your existing IT infrastructure, Amazon VPC will drop any traffic to said range. To avoid this, create your VPC so it does not overlap with current or expected future subnets in your network.
Broadcast and Multicast Unsupported in a VPC You are unable to employ either broadcast or multicast within your VPC.
Ordering of DHCP Option Values Not Guaranteed When you specify DHCP options, some options (e.g., DNS servers) accept multiple values. The ordering of these values is not guaranteed. After creating the options, you should use the DescribeDhcpOptions operation (or the ec2-describe-dhcp-options command) to confirm the order in which the options will be delivered to instances.
Tags for Amazon VPC Resources Not Supported in the Console You can tag your Amazon VPC resources using the API or command line tools, but those tags are not available to work with in the AWS Management Console.
