** Summary changed: - NetworkManager creates bogus default route for interfaces in /etc/network/interfaces without gateway + NetworkManager assigns default route to one of two interfaces despite their both being defined in /e/n/i and managed=false

I have two wired network interfaces (one physical, one tagged (eth0.2) and one untagged (eth0) vlan). Both are configured statically in /etc/network/interfaces. My default gateway is on eth0.2: auto lo eth0 eth0.2 iface lo inet loopback iface eth0 inet static address 172.19.0.33 netmask 255.255.255.0 iface eth0.2 inet static address 145.x.x.x netmask 255.255.255.248 gateway 145.x.x.y Network manager is set not to touch this: [main] no-auto-default=00:15:17:xx:xx:xx [ifupdown] managed=false This used to work fine with jaunty. After the upgrade to karmic NM started to manage these interfaces. But worse, it adds a bogus default route for eth0: 145.x.x.z/29 dev eth0.2 proto kernel scope link src 145.x.x.x 172.19.0.0/24 dev eth0 proto kernel scope link src 172.19.0.33 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 169.254.0.0/16 dev eth0 scope link metric 1000 default via 172.19.0.33 dev eth0 proto static # this is the local IP address default via 145.x.x.y dev eth0.2 metric 100 According nm-applet, ifupdown (eth0) is enabled and ifupdown (eth0.2) is disabled, even though both are up and working. This may be why it adds a default route to eth0 in a desperate attempt to reach at least some hosts, although a high metric would be nice in that case. Even if I add a default route to eth0 with a higher metric, NM still overrides it with a new default route with a zero metric. After start networking but before start network-manager: 145.x.x.z/29 dev eth0.2 proto kernel scope link src 145.x.x.x 172.19.0.0/24 dev eth0 proto kernel scope link src 172.19.0.33 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 169.254.0.0/16 dev eth0 scope link metric 1000 default via 145.x.x.y dev eth0.2 metric 100 default via 172.19.0.65 dev eth0 metric 200 After start network-manager: 145.x.x.z/29 dev eth0.2 proto kernel scope link src 145.x.x.x 172.19.0.0/24 dev eth0 proto kernel scope link src 172.19.0.33 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 169.254.0.0/16 dev eth0 scope link metric 1000 default via 172.19.0.65 dev eth0 proto static default via 145.x.x.y dev eth0.2 metric 100 default via 172.19.0.65 dev eth0 metric 200 The best solution in this case would probably for NM to start honoring managed=false again, although it would be nice if it were somewhat smarter about default routes and interfaces being up (if state=UP, the media state is up and it's got an IP address, it's probably up).
