The ENS driver uses a set of rules to define what type of connection is being received by a WinGate network interface during communication. It takes into consideration what usage WinGate has classified the network interface as having, and the packet details in the actual traffic of the connection.

There are 5 different types of connections that are defined by WinGate:
|
Connection type |
Description |
Firewall default action |
|---|---|---|
Connections from the Internet |
If packet is received on a network interface where its usage is marked as External on the WinGate server, and it's not a previously known connection, then this is considered to be a connection from the Internet. This option is used most commonly for inbound connections from the Internet. |
The default action of the WinGate firewall is to deny all traffic when it receives this type of connection. |
LAN connections to the WinGate PC |
This type of connection occurs when packets are received on a network interface marked as Internal (Trusted network) on the WinGate server, and their destination is the local WinGate machine IP address. |
The default action is for the firewall to allow these packets. |
LAN connections to the Internet |
This type of connection happens when packets are received on a network interface marked as Internal or DMZ on the WinGate server, which are NOT destined for WinGate, but where their matching route implies that the packet would need to be forwarded out an interface marked as External or DMZ - e.g. Normal NAT, Internet requests. This is the most common connection for clients making ordinary outgoing Internet requests, such as HTTP,FTP etc. and the default action for the WinGate firewall is to allow these connections. |

Connections from the Internet to DMZ computers |
This type of connection happens when packets are received on a network interface marked as External on the WinGate Server, and their destination is to an adapter marked as a DMZ adapter. |
The default action for this type of connection is to deny these types of connections. |
Connections from DMZ to the WinGate PC |
This type of connection occurs when the packets sent by machines connected to the DMZ are received by the WinGate DMZ adapter but where their destination is WinGate IP address (LAN). |
The default action is to allow these types of connections. |
When configuring filters in the Port Security tab of the Extended Network Driver properties, you are required choose the connection type that will be affected by the filter.
