For some days now I am trying to figure out what is the problem and
IceHouse instances don't get internet access (you can have a look here:
Today I 've discovered that I have to put a NAT-firewall rule in the
compute node every time I start an instance. The rule that is needed is:
iptables -t nat -I POSTROUTING -o eth0 -j MASQUERADE
If I put the rule and then I start an instance then the instance
doesn't have internet connectivity unless I put the rule again. The same
applies if I start a second instance! All of them are loosing
internet-connectivity. Putting the rule again and all of them are
connected again. And the same happens again and again.
Is this a bug somewhere??? Am I missing something??
You all understand that it's not convenient at all to have to execute
this every time an instance is started!
Looking forward to hear your thoughts!
