Package: netbase
Version: 3.14-3
After I shutted down an interface:
ifconfig eth1:6 down
I still was able to make ping to IP that card represented.
Only after I killed redirector of an port from that IP to
IP on local network (NAT firewall), I wasn't able nor
to ping, nor to use that port.
Fix it to kill interface anyway, even if somebody has listenning
sockets on it.

closing as this is based on the linux networking model
see for instance
http://www.mail-archive.com/linux-net@vger.kernel.org/msg01235.html
Q: Why can I ping an IP address when the interface is down?
A: Linux uses a "host based" addressing model, IP addresses are owned by
the host, not individual interfaces. So as long as the IP address is
configured to some interface, we will accept packets destinated to that IP
address as our's.
