Modify the default security group

This section details the procedure for modifying the default security group to allow access to port 3333.

This example shows how to modify the default security group to allow port 3333 access from anywhere. Connections to the Elastic IP address on port 3333 are translated by the Vyatta NAT device and then routed to the private instance that is created in a later step.
