All IP addresses within a 10.0.0.0/16 VPC are fully utilized with application servers across two Availability
Zones. The application servers need to send frequent UDP probes to a single central authentication server

servers to use a single NAT gateway for internal access. Testing reveals that a few of the servers are
unable to communicate with the authentication server.
