Ssh Screen - ZyXEL Communications LTE7410 User Manual

If an outside user attempts to probe an unsupported port on your LTE Device, an ICMP response
packet is automatically returned. This allows the outside user to know the LTE Device exists. Your
LTE Device supports anti-probing, which prevents the ICMP response packet from being sent. This
keeps outsiders from discovering your LTE Device when unsupported ports are probed.
Note: If you want your device to respond to pings and requests for unauthorized services,
you will also need to configure the firewall accordingly by disabling SPI.

You can use Secure SHell (SSH) to securely access the Device's command line interface. Specify
which interfaces allow SSH access and from which IP address the access can come. SSH is a secure
communication protocol that combines authentication and data encryption to provide secure
encrypted communication between two hosts over an unsecured network.
