I am trying to build a fallback connection for my ubuntu box on eth1 (it is actually a Huawei HiLink mobile broadband modem). This is the content of my interfaces file:
auto lo
iface lo inet loopback
auto eth0
allow-hotplug eth0
iface eth0 inet manual
auto eth1
allow-hotplug eth1
iface eth1 inet manual
metric 400 # does not work
I am using dhcpcd as networkmanager. I have read that dhcpcd automatically sets the metric of ethernet devices to 200+ and of wlan devices to 300+. Here is my output of route -n:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.42.0.1 0.0.0.0 UG 202 0 0 eth0
0.0.0.0 192.168.1.1 0.0.0.0 UG 203 0 0 eth1
0.0.0.0 192.168.0.1 0.0.0.0 UG 304 0 0 wlan0
10.42.0.0 0.0.0.0 255.255.255.0 U 202 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 304 0 0 wlan0
192.168.1.0 0.0.0.0 255.255.255.0 U 203 0 0 eth1
Is it possible to change metric in dhcpcd elsewhere? Because in the interfaces file it simply does not work!
