In this example, the route table is created for PVS-Deployment-VPCand is associated with the PVS-Deployment-Public subnet.

Use of NAT also complicates tunneling protocols such as IPsec because NAT modifies values in the headers which interfere with the integrity checks done by IPsec and other tunneling protocols. PAT (Port Address Translation) resolves conflicts that would arise through two different hosts using the same source port number to establish unique connections at the same time. For the ping command to work, the rules must also allow outbound ICMP traffic.Note The NAT gateway itself allows all outbound traffic and traffic received in response to an outbound request Click the Create new subnet button to configure the instance's subnet.

Create a NAT gateway in each Availability Zone to ensure zone-independent architecture. Ensure that your security group rules allow inbound SSH traffic from the private IP address of your instance that you launched in the public subnet, and all outbound ICMP traffic.
