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:

CONTROLLER:
eth0:89.139.232.98/24 connected to external switch with gateway 89.139.232.1
br100: takes IP address 192.168.1.2 after nova network-create
eth1:10.1.1.112/8 connected to internal switch

COMPUTE:
eth0:no IP, created br100 what takes IP 192.168.0.1 after VM is created
eth1:10.1.1.111/8 connected to internal switch

In compute node /etc/nova/nova.conf related to network:
my_ip = 10.1.1.111
firewall_driver = nova.virt.libvirt.firewall.IptablesFirewallDriver
network_manager = nova.network.manager.FlatDHCPManager
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 192.168.0.0/16 --bridge=br100 --bridge-interface=eth0 --multi-host=T

When I assign floating IP 89.139.232.100 to VM, I can ping it and all compute IPs, but not ISP gateway 89.139.232.1
Does anyone see what am I doing wrong here ?

Thanks a lot for any help, Rast'o
