Hi, I have a system with two network interfaces, connecting to two subnets.
For some reason the default route is going through eth0.3, I would want to have it through eth0.7. Is the default route determined by the order in /etc/network/interface of the interfaces or is there another algorithm behind? rd@master:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.
