About EF TUNNEL

1. Through the application it is possible to customise the start of the connection (we call injection) with typed connection text (HTTP standard or any other), or setting an SNI to perform handshaking with the server.

2. EF TUNNEL uses existing connection protocols such as OPENVPN BASE.

3. This is very useful for crossing restrictions imposed by internet providers or any network that you are using during the connection.

4. All traffic generated between the client and the server is protected with OPENVPN BASE.

5. Each user is given a randomly generated ID by the application to connect to the server.

6. The configuration file has the . hat extension, it is an encrypted text file containing all the information that was defined before exporting it.

7. You can import and export the connection method settings.

8. When exported, you can set a message for who imports and lock it so that the method setting is not visible or editable.
