Your entire network will appear to the outside world as a single computer. (Canny network gurus can penetrate NAT firewalls, but it isn't easy.) Source NAT (SNAT) rewrites the source addresses of all outgoing packets to the firewall address. It works the other way as well.
Source Network Address Translation. This is what most home routers do. SNAT replaces the source IP address with the address of the external-facing interface. The inverse to SNAT is Destination NAT. The SNAT target requires you to give it an IP address to apply to all the outgoing packets. The MASQUERADE target lets you give it an interface, and whatever address is on that interface is the address that is applied to all the outgoing packets. Aug 07, 2015 · Source Network Address Translation (SNAT) Source Network Address Translation (SNAT) maps internal IP (private IP) addresses to an external IP (public IP) address. SNAT re-writes the IP address of the computer that originated the packet. SNAT is composed of two steps: The process of translating an internal IP address into an external IP address; An SNAT rule translates the source IP address of packets sent from an organization VDC network out to an external network or to another organization VDC network. A DNAT rule translates the IP address and, optionally, the port of packets received by an organization VDC network that are coming from an external network or from another organization

SNAT is necessary because the internet gateway only knows how to translate between the primary private and public or elastic IP address assigned to the primary elastic network interface of the Amazon EC2 instance node that pods are running on.
The Network Monitor capture files of the above SNAT flow can be downloaded from: Worker Instance side capture; Internet Server side capture; SNAT ports exhaustion. SNAT load balancer is a shared resource between all of App Service sites in the same stamp. Including the web applications, WebJobs, Functions, telemetry services (Application
NAT Gateway provides Source Network Address Translation (SNAT) and Destination Network Address Translation (DNAT) functions for Elastic Cloud Servers (ECSs) in a Virtual Private Cloud (VPC), making it easier for you to configure the ingress and egress for a VPC. Iptables and NAT, SNAT, and DNAT - Networking Tutorial Your entire network will appear to the outside world as a single computer. (Canny network gurus can penetrate NAT firewalls, but it isn't easy.) Source NAT (SNAT) rewrites the source addresses of all outgoing packets to the firewall address. It works the other way as well. iptables - Difference between SNAT and Masquerade - Unix The SNAT target requires you to give it an IP address to apply to all the outgoing packets. The MASQUERADE target lets you give it an interface, and whatever address is on that interface is the address that is applied to all the outgoing packets. In addition, with SNAT, the kernel's connection tracking keeps track of all the connections when the interface is taken down and brought back up; the
