I seem to have the cellular network up… but I can’t ping through it. Any suggestions?

Thanks

However pinging through that interface doesn’t seem to work. Am I doing something wrong? I’ve tried both 1.1.1.1 and 8.8.8.8 .

$ ping -I 192.168.225.49 1.1.1.1
PING 1.1.1.1 (1.1.1.1) from 192.168.225.49 : 56(84) bytes of data.
^C
--- 1.1.1.1 ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7145ms

Also tried this with nothing received:

$ mosquitto_sub -h test.mosquitto.org  -t "#" -A 192.168.225.49
^C

This ping seems to work:

pi@cellularm:/opt/sixfab/core/manager/core_manager/helpers$ ping -I wwxfe9a5d9xxxxx 1.1.1.1

Putting the interface name in for the -A parameter on mosquitto_pub gives me a lookup error.

pi@cellularm:/opt/sixfab/core/manager/core_manager/helpers$ mosquitto_sub -h test.mosquitto.org  -t "#" -A wwxfe9a5d9c1120
Unable to connect (Lookup error.).

Hopefully someone has gone here before.

Thanks.
