For guidance on mitigation of SNAT port exhaustion, see [Support and troubleshooting for Azure Load Balancer](./load-balancer-support-help.md).
 
 ## Port reuse
 For TCP connections, the load balancer uses a single SNAT port for every destination IP and port. For connections to the same destination IP, a single SNAT port can be reused as long as the destination port differs. Reuse isn't possible when there already exists a connection to the same destination IP and port.
