I'm trying to create multiple subnets on a Wheezy server, where I can run multiple virtual machines off of each subnet. Initially, I'd like to create 2 and I've gotten one of the subnets working, but can't seem to get the second one going.
My /etc/network/interfaces includes:
iface eth0 inet manual
up ip link set $IFACE up promisc on
down ip link set $IFACE down promisc off
iface dummy0 inet static
iface dummy1 inet static
iface dummy0:245 inet static
iface dummy1:1 inet static
I can ping 10.1.1.245 and the virtual machine has connectivity, but I cannot ping 10.1.2.1 or 10.1.2.111.
FYI: along the way, I have tried disabling ipv6 and adding:
echo "options dummy numdummies=2" > /etc/modprobe.d/local
Any suggestions as to how to fix this? Thanks!
