About Secure Remote Telnet Access and SSH

Default Telnet service configuration

The SpeedTouch™ Telnet host is provided by the SpeedTouch™ Telnet server. Access to this server and hence the Telnet interface is controlled by the Telnet service. By default, the Telnet service is configured to let the Telnet server accept telnet sessions from LAN side only. In addition the SpeedTouch™ provides SSH remote access.

SSH provides a more secure way of accessing the SpeedTouch™ CLI interface and should therefore be used.

Use the following CLI command to see the default Telnet service configuration.

=>:service system list name=TELNET expand=enabled			Group	State
Idx Name	Protocol	SrcPort DstPort

--------------------------------------------------------------------

1 TELNET	tcp	23	enabled
	Description		Virtual Terminal
	Properties		server
	Managed parameters		state port acl map log
	Interface Access List		lan
	Ip Access List		any
=>	NAT Port List		23

Configuration via CLI commands

To have Telnet access via WAN, additional configuration of the SpeedTouch™ Telnet service is needed.

Use the following CLI command to allow WAN Telnet access to the SpeedTouch™.

=>:service system ifadd name=TELNET group=wan =>

Use the following CLI command to take a look at the Telnet service configuration, you will see that the wan group is added to the Interface Access List:

=>:service system list name=TELNET expand=enabled
