Azure Load Balancer TCP resets on idle timeout is now available

Published date: February 26, 2020

Azure Load Balancer now supports sending bidirectional TCP resets on idle timeout for load balancing rules, inbound NAT rules, and outbound rules. This is available in all regions. 

Use this ability to help applications gain visibility into when Standard Load Balancer terminates connections due to idle timeout. When enabled, Standard Load Balancer will generate a TCP reset packet to both the client and server side of a TCP connection on idle timeout. This allows applications to behave more predictably, as well as to detect the termination of a connection, remove expired connections, and initiate new connections.  

TCP resets can be enabled on standard load balancers using the Azure portal, Resource Manager templates, CLI, and PowerShell.
