Payment traffic had to leave through a managed security appliance while the site already operated on a different gateway platform.
Infrastructure / CASE STUDY
A new payment path. The existing network.
Point-of-sale migration behind a security appliance
MY CONTRIBUTION
Implemented the point-of-sale routing path and documented an alternative migration design for the client.

Implemented · specified payment route
Payment traffic passes through the required security appliance. The existing gateway and the rest of the site network remain in place.
Use 1:1 NAT and a transit handoff from the existing gateway to route payment traffic through the required appliance, preserving the rest of the site network.
A deployed payment-traffic path meeting the specified vendor routing requirement, plus a written alternative using WAN2, policy-based routing, NAT masquerade, and firewall rules.
The additional-appliance path was implemented. The single-gateway path is a documented future option, not a deployed configuration. The public topology uses recreated devices and example addressing.
