 ### How to analyze outbound connectivity
 
-To analyze outbound traffic from NAT gateway, use NSG flow logs. NSG flow logs provide connection information for your virtual machines. The connection information contains the source IP and port and the destination IP and port and the state of the connection. The traffic flow direction and the size of the traffic in number of packets and bytes sent is also logged.
+To analyze outbound traffic from NAT gateway, use NSG flow logs. NSG flow logs provide connection information for your virtual machines. The connection information contains the source IP and port and the destination IP and port and the state of the connection. The traffic flow direction and the size of the traffic in number of packets and bytes sent is also logged. The source IP and port specified in the NSG flow log will be that of the virtual machine and not of the NAT gateway.

 ### IPv6 coexistence
 
-[NAT gateway](nat-overview.md) supports IPv4 UDP and TCP protocols. NAT gateway can't be associated to an IPv6 Public IP address or IPv6 Public IP Prefix. NAT gateway can be deployed on a dual stack subnet, but will still only use IPv4 Public IP addresses for directing outbound traffic. Deploy NAT gateway on a dual stack subnet when you need IPv6 resources to exist in the same subnet as IPv4 resources.
