Ingress Directly through Firewall
Another often configured Ingress Egress design pattern is to have the traffic forward to firewall instances directly as shown in the diagram below. In this design pattern, each firewall instance must configure SNAT on its LAN interface that connects to the Aviatrix FireNet gateway. The drawback of this design is that the source IP address is not preserved when traffic reaches the application. If you need to preserve source IP address, refer to this recommended design for Ingress.

Ingress Protection via Aviatrix Transit FireNet
This Ingress Protection design pattern is to have the traffic forward to firewall instances directly in Aviatrix Transit FireNet VPC/VNet as shown in the diagram below. In this design pattern, each firewall instance must configure (1) SNAT on its LAN interface that connects to the Aviatrix FireNet Gateway and (2) DNAT to the IP of application server/load balancer. The drawback of this design is that the source IP address is not preserved when traffic reaches the application.
