Доброго времени суток!
Никогда не думал что пригодится, но на cisco привык юзать loopback интерфейсы,
аналогом которых в линукс и есть dummy. Краткое howto, что-бы не забыть.

tail /etc/net/ifaces/dummy0/*
==> /etc/net/ifaces/dummy0/ipv4address <==
192.168.192.132/32

==> /etc/net/ifaces/dummy0/options <==
DISABLED=no
ONBOOT=yes

#modprobe duumy
#echo dummy >> /etc/modules
# ifup dummy0
/sbin/modprobe: invalid option -- 'o'
Usage: /sbin/modprobe [-v] [-V] [-C config-file] [-d <dirname> ] [-n] [-i] 
[-q] [-b] [-o <modname>] [ --dump-modversions ] <modname> [parameters...]
/sbin/modprobe -r [-n] [-i] [-v] <modulename> ...
/sbin/modprobe -l -t <dirname> [ -a <modulename> ...]
Cannot find device "dummy0"

типа того приехали...
