 #### Source (SNAT) port reuse
 
-Azure provides ~64,000 SNAT ports per public IP address. For each public IP address attached to NAT gateway, the entire inventory of ports provided by those IPs is made available to any virtual machine instance within a subnet that is also attached to NAT gateway. NAT gateway selects a port at random out of the available inventory of ports for a virtual machine to use. Each time a new connection is made to the same destination endpoint over the internet, a new source port is used. As mentioned in the [Performance](#performance) section, NAT gateway supports up to 50,000 concurrent connections per public IP address to the same destination endpoint over the internet. NAT gateway will continue to select a new source port at random to go to the same destination endpoint until no more SNAT ports are available for use. If NAT gateway doesn't find any available SNAT ports, only then will it reuse a SNAT port. A port can be reused so long as it's going to a different destination endpoint.

 NAT gateway opportunistically reuses source (SNAT) ports. When you scale your workload, assume that each flow requires a new SNAT port, and then scale the total number of available IP addresses for outbound traffic. Carefully consider the scale you're designing for, and then allocate IP addresses quantities accordingly.
 
-SNAT ports set to different destinations will most likely be reused when possible. As SNAT port exhaustion approaches, flows may not succeed.
