How to connect to outside world from amazon vpc?
It appears that the only way to get outside from instances that don't have Elastic IP is:
- add a NAT (Launch an extra m1.small instance from ami-vpc-nat-beta) and assign EIP to it
- Create an extra subnet which will be "private"
- Move non-EIP-instances to that private subnet
- Modify route tables: 0.0.0.0/0 from the private subnet should go to NAT
So, just adding NAT is not enough. Instances should be stopped and moved to another IP from another subnet.
The docs tell you should add a NAT Instance
