내 프로젝트에는 모바일 인터넷이 필요합니다. M2M 시뮬레이션(공용 IP, NAT 없음)과 함께 LTE 스틱 모뎀을 사용하여 이를 달성하려고 합니다.
이것은 ubuntu(5.3.0-29-generic)에서는 잘 작동하지만 Raspbian Buster(4.19.97+)에서는 작동하지 않습니다.

이를 위해 wvdial과 다음 설정을 사용해 보았습니다.
[Dialer Defaults]
Auto DNS = yes
Init1 = ATZ+CFUN=1
Init2 = ATH
Init3 = ATE1
Init3 = AT+CGDCONT=1,"IP","EEM2M"
Stupid mode = 1
Baud = 9600
Dial Command = ATD
Modem = /dev/ttyUSB1
ISDN = 0
Phone = *99#
Password = bt
Username = bt
NetworkManager.conf에는 다음 내용이 있습니다.
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
ppp/resolv.conf에는 다음 내용이 있습니다.
nameserver 109.249.185.224
nameserver 109.249.186.32
나는 이것이 설정에 의해 설정된 것 같아요 (위의 로그 참조)
마지막으로 이것은 wvdial이 실행된 후 ifconfig -a를 실행하는 것을 보여줍니다. ppp0의 6개 패킷은 10.217.44.214에 대한 내부 핑입니다.

또한 wvdial을 실행하면 NetworkManager가 /etc/resolv.conf에 올바른 DNS를 로드하여 변경되는 것으로 나타났습니다.

답변1
비슷한 문제에 직면하여,
sudo route add default ppp0
나를 위해 작동합니다.
이 프로세스를 자동화해야 하는 경우 연결이 설정될 때 실행될 스크립트를 /etc/ppp/ip-up.d에 만들 수 있습니다.
