Network Address Translation (NAT) is one of three connection methods clients can use to access the Internet through WinGate. With little configuration or overhead, NAT is a simple but effective way to give clients access regardless of what Internet application they are using.
To use NAT, WinGate clients are simply required to have their gateway set to the LAN IP address of the WinGate server and have access (on the LAN) to a suitable DNS server for DNS lookups if they are needed.
A NAT client can be any computer that uses TCP/IP networking, regardless of operating system. This makes it ideal for LANs that have a mix of operating systems that require Internet access. WinGate NAT will handle connections from Windows, MAC, and UNIX machines that communicate using TCP/IP.

NAT is enabled by default. To disable NAT:
Once NAT has been disabled, clients will need to use one of the other client connection methods, in order to access the Internet through WinGate.
The ENS driver provides NAT services for WinGate, and so NAT will not be available if you disable or remove the ENS driver.
Due of the light weight approach of Network Address Translation, NAT clients cannot be controlled as easily as users who have configured their applications to use a WinGate proxy service, or those who have WGIC installed on their machines.
A few WinGate network services offer the Intercepting Proxy feature on the Intercepting tab of their properties, which can be made to listen for ALL traffic on a selection of different ports. Any request received by WinGate on a port listed on a Intercepting Proxy tab will be subjected to the controls and features of the particular proxy service where Intercepting Proxy is set. This means that client NAT connections made through WinGate to a particular port, can be intercepted by the relevant network service and processed the same way as a normal proxy request.
The NAT client will be put through any controls and handling from any event processors that have been configured to respond to the events registered by the particular proxy service. This allows you to utilize the easy set up for NAT clients, and the power of the WinGate network proxy services when managing client connections.
