Hi Kyson,
yes, the modem internal address is pingable from the module itself…
root@imx8mm-var-dart:~# ifconfig

I tested also to ping the modem gateway ( 192.168.225.1 )…
(from “nmcli con show usb0”…)
…
IP4.ADDRESS[1]: 192.168.225.21/24
IP4.GATEWAY: 192.168.225.1

and it works…

Also if I test (from the module) a traceroute command, works…

however seems not passing from the public address (in this case 91.xx.xx.11)
Update: yesterday I tested the EC25 modem (mounted on the evk) using a linux PC (lubuntu) and the result is the same…the public address is reachable , the ports are all closed.
Thanks, have a nice day.
