I run this command to get the the internet working on a server of mine. 184.108.40.206 represents the gateway for the VLAN. What do I have to do to make this change survive a reboot?
/sbin/route add -net 0.0.0.0 gw 220.127.116.11 eth0
That depends on your distribution.
If it's a Debian-derivative or Red Hat-derivative, edit
On next reboot, it will be set.
