AMG1302/AMG1202-TSeries exists. Your AMG1302/AMG1202-TSeries supports anti-probing, which

prevents the ICMP response packet from being sent. This keeps outsiders from discovering your

AMG1302/AMG1202-TSeries 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.

provide secure encrypted communication between two hosts over an unsecured network.
