Description

Disclaimer

Known affected version(s) were inferred because the vendor did not provide any: 4.2.3.1

Overview

When the DNS forwarder forwards traffic to an upstream server, the UDP source port may conflict with the NSX DP reserved port in rare cases. As a result, the response traffic fails to reach the DNS forwarder and the name resolution times out.
