Verified end-to-end with a real login from two sites. This partially reverses the 2026-08-12 hardening on a box still running the **EOL, actively-exploited FortiOS 7.2 branch** — so the exposure is CVE-shaped, and time-boxing it is the mitigation. Re-close = `config system interface / edit wan1 / set allowaccess ping / next / end`. Config backups pre+post at `/var/tmp/ana-gw-config-20260823T20*.conf` on nh3-dev. **Two follow-ons:** (a) ACME renewal for that cert needs **port 80** on wan1 — currently absent, next attempt ≈2026-09-27, expiry 2026-10-27; (b) ~5 SYN/s from `179.51.184.0/21` now draws SYN-ACKs, CPU impact nil, unmitigated by choice. Detail + the FortiOS trusthost gotchas: auto-memory `reference_fortigate_ana_gw_access`. - **⏳ THE OPEN ITEM: Anaheim's IPsec tunnel delivers ~25% of a verified 2 Gbps circuit.** Circuit measured at **2,153 Mbit/s**; the tunnel ceilings ~550 Mbit/s aggregate, ~230 single-stream. FortiGate CPU **idle**, IPsec **NPU-offloaded**, interface error-free — so it is not crypto exhaustion. Both tunnels negotiate **`aes256-sha1`**; **AES-GCM is the proposed change** and the operator has signalled he will authorize it. Not executed: production edge, needs a matching change at NH3 + ESH, each tunnel drops during renegotiation. → `persistent-memory.d/2026-08-23-anaheim-ipsec-tunnel-ceiling.md`
