DMZ setup on Transit VPC (AWS)

L1 Bithead

I'm just wondering if anyone setup a DMZ on Transit firewalls in Transit VPC on AWS? Basically we need to have outbound to inbound NAT rule with a elastic ip address. Came across this link but not sure if this is the proper way of doing it. We would like achieve this through a dedicated VSYS but open for different options.


The design on page 12 of that guide utilizes a separate set of firewalls in the spoke VPC that are dedicated to the inbound traffic for only that spoke VPC.  This design is different than bringing inbound traffic in through the Transit VPC.  In either scenario, the EIP/FQDN is assigned to the public-facing load balancer, it is not released if a link is down.  The design you are looking for is not in that guide.  It would be best communicated through your Systems Engineer.
