PowerDNS Load Testing Fails within AWS VPC #6
Description
Hey there!
We are attempting to determine the maximum traffic our PowerDNS-Auth server can handle within AWS. The load testing tool utilizes MAC addresses to send traffic, which is causing issues within the VPC environment.
The current command is configured with a valid MAC address, but no traffic reaches the PowerDNS-Auth server. We observe that the isc-dnsgen binary consumes significant CPU resources, yet fails to generate and send network packets. Consequently, no traffic is detected on the recipient side of the connection.
The AWS Security Group setup is currently configured to allow all traffic. However, attempts to use arping result in a timeout, indicating a failure to send packets.
This behavior may be an expected limitation, as AWS typically restricts ARP traffic between instances in the same subnet unless specific internal AWS services are utilized. We are currently unable to execute meaningful load tests due to this limitation.
Could anyone suggest a workaround for this?
Thanks!
