[ ~ ] route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         0.0.0.0         0.0.0.0         U     0      0        0 ppp0
                                ...
                                ...

如果没有default到ppp0的这条路由,需要手动创建:

1
sudo route add default dev ppp0
