Any unsolicited requests or data packets are discarded, preventing communication with potentially dangerous devices on the internet. We first need to select the one public subnet and grant that nat gateway an elastic ip address. Very good post, SNAT is really flexible and works well, making it source IP transparent can be done IF the load balancer is the default gateway, but then if the load balancer was the default gateway you could just use simple layer 4 NAT mode which is obviously faster. configured with a NAT gateway allowing instances to reach out to the public internet to get software updates, but they don't. As far as NAT gateway vs. A TGW allowed a ‘full mesh’ of routes to be passed between VPCs and VPN terminations which were not reliant on the VPC peering (with its transitive routing limitations) providing the ability to connect thousands (up to 5000) of VPCs and on-premises networks together, across multiple accounts to a single gateway.
