Using Amazon Virtual Private Cloud : Configuring security groups : Connecting to the VPC through the VPN (without NAT)
  
Connecting to the VPC through the VPN (without NAT)
Configure a VPC through the VPN by modifying the security group of the AWS EC2 instances running the Discovery Agent:
1. Add the private IP address of the remote server for the ports used by the application to optimize.
2. Add the security group of the SteelHead-c (enable access to all ports).
3. On the SteelHead-c security group, add the public IP address of the remote SteelHead and enable it to access port 7800 and port 7810.
