What is the name of the domain?
1.1.1.1, 1.0.0.1
What is the issue you’re encountering
My linux(raspberry pi os) device does not have any trouble in wlan network. But if i activate cellular network (via eth2 interface), it pings to 8.8.8.8 in success but cannot ping to 1.1.1.1, 1.0.0.1 or google.com. My cellular network provider is “vodafone IT Twilio”. Also this causes udp resolve error in my project: “failed to resolve UDP address: lookup foo on 1.0.0.1:53: read udp xxx.xxx.xxx.xx:xxxxx->1.0.0.1:53: i/o timeout”
What steps have you taken to resolve the issue?
Traceroute outputs:
~# traceroute 1.1.1.1 -i eth2
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 60 byte packets
