I have two internet connections. One is from ADSL router (eth0) and another one is from 4G LTE USB stick. When I connect USB stick I see two routing entries
ip route show
default via 192.168.1.1 dev eth0 proto static metric 425 default via 103.x.y.z dev wwx001e101f0000 proto static metric 700
Because of metric traffic always go through eth0. There is case when I need to route traffic using wwx001e101f0000 interface of USB 4G LTE stick. How can I change that without disconnecting eth0? Is it possible to change routing metric for wwx001e101f0000 to say ‘200’ so that route traffic via that interface when connected?
