====== Telnet CLI ======
The Internet Gate has a powerful Command Line Interface, accessible through [[wp>Telnet]], allowing advanced users make complex configurations not possible using the [[:web GUI:main menu|web GUI]].

^ For advanced users only! ^
| Incorrect CLI commands can render your unit uncontactable or even permanently damaged! |

:!: By default Internet Gate's firewall stops all attempts of connecting to the Telnet CLI from the outside (WAN/Internet) network. 
  * Before you can use the CLI for remote users you must enable Telnet access by checking the **Remote configuration (Telnet)** on [[*web GUI:security profile#Allowed applications|security profile]]. (You must also enter an IP address and mask to allow only one or a few remote users, to stop unwanted attacks)
  * For local (LAN) users the Telnet access is enabled by default. It could be turned off by unchecking the **Administration (Telnet)** on [[*web GUI:security profile#Applications from inside|security profile]].

===== Login =====
Log in to Telnet CLI by opening a telnet connection to one of Internet Gate's addresses: Write **%%telnet 192.168.0.1%%** in a Windows Command Prompt or use a [[wp>Telnet#Telnet_clients|Telnet client]].

Username is **admin** and password is the same as admin's password for access of the [[:web GUI:start|web GUI]].

===== Help =====
For a list of available CLI commands type **?**

The CLI has **TAB completion** meaning you can press TAB to finish a partly entered command or argument, and displaying a list of available choices if pressing TAB twice.

To quit CLI (and the Telnet session) enter **user logout**.

===== Console =====
The system console is a lower-level CLI, accessible by the **console enable** command.
