The MTX-Tunnel firmware has TACACS + authentication support as of version 9.26. That is, it is possible to use a Tacacs + server to authenticate a user who wants to use the Telnet or SNMP service.
It will be necessary to configure the TELNET_auth or SNMP-auth parameter with the “tacacs +” option in order to use this functionality.

Enter the “ethernet” or “modem” connection type:
For an ethernet configuration, make sure the IP parameters are compatible with server access according to the concentrator local network configuration. For an ethernet connection, the configuration must be compatible with the concentrator’s local network topology so that it can access the servers. This configuration is done from the “Networks” configuration page (see section 3.2.2.3: “Networks”).
For a modem connection, the modem configuration must be correct before a connection can be set up. This configuration is done from the “Modem” configuration page (see section 3.2.2.4: “Modem”).
The parameters for the servers to be configured are at least the following:
Therefore the following fields need to be configured: “Interface”, “Type”, “Server type”, “Address”, “Port”, “Login” and “Password”.
The other fields can be left at the default values subject to the directories having been properly created beforehand. See section 3.1.2: “Configuration files” for more details.
Wait. The concentrator will reboot using its factory configuration.
Esperar. El concentrador arrancará con su configuración de fábrica.
Warten Sie. Der Hub startet nach ein paar Augenblicken mit der Werkseinstellung neu.
Attendre. Le concentrateur va redémarrer avec sa configuration usine.
