I second Tony Maro: 10.10 does not add any masquerading for the node controllers. A quick workaround that works for me is adding in /etc/rc.local:
iptables -t nat -A POSTROUTING -s 192.168.42.0/24 -o eth1 -j MASQUERADE iptables-save> /var/run/eucalyptus/net/iptables-preload Here, my node controllers are in the .42.0/24 private network, using the CC as gateway (CC is connected to the network via eth0). Eth1 of the CC is connected to the outside word. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus in Ubuntu. https://bugs.launchpad.net/bugs/579868 Title: Unable to use Eucalyptus' iptables-preload feature with UEC -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
