Hi guys,

I know its been discussed a lot here about this and I browsed many threads, but still cant figure out, why my VM is not accessible from outside. Here is my topology and configuration in Kilo:

eth0: connected to external switch with gateway
br100: takes IP address after nova network-create
eth1: connected to internal switch

eth0:no IP, created br100 what takes IP after VM is created
eth1: connected to internal switch

In compute node /etc/nova/nova.conf related to network:
my_ip =
firewall_driver = nova.virt.libvirt.firewall.IptablesFirewallDriver
network_manager =
allow_same_net_traffic = False
multi_host = True
send_arp_for_ha = True
share_dhcp_address = True
force_dhcp_release = True
flat_network_bridge = br100
flat_interface = eth0
public_interface = eth0

I create network like:
nova network-create demo-net --fixed-range-v4 --bridge=br100 --bridge-interface=eth0 --multi-host=T

When I assign floating IP to VM, I can ping it and all compute IPs, but not ISP gateway
Does anyone see what am I doing wrong here ?

Thanks a lot for any help, Rast'o
