and will re-generate the HOME_NET file, to take care if the IP-address of this
interface has changed.

Unbound was trying to check availability of the upstream name servers
when /var/ipfire/red/active is present. This patch removes it first
and then brings down the red device.

Some hosters have their gateway in a different subnet than
the RED interface is to save IPv4 address space.
This patch sets a host route to that gateway so that
IPFire can be installed in data centres that use such
technique.
