A customer is migrating from a FortiWAN to a Peplink. The existing FortiWAN setup has a one-to-one mapping between ISPs (WANs) and LANs, with at least two such mappings. While routing is not necessary, the Peplink is expected to handle NAT for HTTP/HTTPS traffic. All other NAT functions are performed by the downstream firewall.
We are exploring two potential solutions:
- A Drop-IN architecture, but due to architectural constraints, this option seems impractical.
- IP-Passthrough, which we have not implemented before.
We would like to gather input on the best approach for this scenario.
