 Each NAT gateway can provide up to 50 Gbps of throughput. You can split your deployments into multiple subnets and assign each subnet or group of subnets a NAT gateway to scale out.
 
-NAT gateway can be attached to up to 16 public IP addresses. Each NAT gateway can support up to 50,000 concurrent connections per public IP address to the same destination endpoint over the internet for TCP and UDP. Review the following section for details and the [troubleshooting article](./troubleshoot-nat.md) for specific problem resolution guidance.

 #### 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 to make new outbound connections. If NAT gateway doesn't find any available SNAT ports, then it will reuse a SNAT port. A port can be reused so long as it's going to a different destination endpoint. 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.
