Not hacking on that script was why I proposed adding /etc/dhcp3/dhclient-enter-hooks.d/no-default-route instead. That way the original script isn't changed. But it is controlling that script from the outside. By adding that script which gets sourced by the other. If your /etc/network/interfaces uses static addresses doesn't have a gateway and it is a static route then it shouldn't be added. If your /etc/network/interfaces uses dhcp addresses then one pretty much unconditionally gets added by the dhclient-script unless you take steps to prevent it. Or you could remove them after the fact as you have been trying to do. > route del -net 10.5.2.0/24 gw 0.0.0.0 dev vlan52 > > But this removes the static route instead!
