vm instance cannot not be connected to internet

[viswacse02]

I have setup a private cloud using two machines using uec 10.04. I can access the vm instances from the NC. The problem is i cannot connect the vm instance with internet because i have to install netbeans ide or java compiler on the vm install and get service from it.

Is there any solution to this problem?


The ultimate aim is to install netbeans or jdk on vm instances for which internet is needed to update the vm instances. I suddenly got an idea to copy the netbeans ide or jdk which is downloaded from internet in the node controller (nc) machine to vm instance. Is it possible to copy the files from nc to vm instances? I do know because i am new to this environment. I first all tried to copy a small file from nc to vm instances using scp but couldn't.

Hi,
Can you please try executing the 2 following commands on the CLC/CC node

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

I am assuming eth0, is the "outer" interface connecting to the internet. if it's not, change the name to the appropriate one.
