Azure Load Balancer TCP resets on idle in preview
Posted on 24 September 2018
Now in preview, Azure Load Balancer supports sending of bidirectional TCP resets on idle timeout for load balancing rules, inbound NAT rules and outbound rules.
Use this new 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 for the client and server side of a TCP connection on idle timeout. This allows applications more predictable behaviour, 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 Resource Manager templates, CLI and PowerShell.
