A pfSense NAT rdr rule redirects `10.0.20.203:{25,465,587,993}` → `10.0.20.1` (mail HAProxy) on any incoming interface, so LAN mail clients land on the right service unchanged.

+- **Known mail-name collision**: the translation also sends `mail.viktorbarzin.me` (and `imap.`/`smtp.`) to `.203`, but Traefik does not listen on mail ports there. iOS Mail on Barzini WiFi silently hangs. Fix in flight: dedicated pfSense Virtual IP for the mail listener so DNS can point at a stable mail-only IP instead of relying on Traefik's LB IP.

-<?php
-// pfSense NAT — LAN-side redirect for mail ports landing on the Traefik LB IP.
-//
-// WHY THIS EXISTS
-//   Technitium serves Barzini WiFi (192.168.1.0/24) clients a split-horizon
-//   answer: `mail.viktorbarzin.me CNAME viktorbarzin.me A 10.0.20.203`.
-//   .203 is Traefik's dedicated LB IP — it serves Roundcube on :443 but does
-//   NOT listen on mail ports. iOS Mail (which uses 993/465/587) silently
-//   hangs.
-//
-//   Existing pfSense rules redirect WAN-IP:{25,465,587,993} -> 10.0.20.1
-//   (pfSense's mail HAProxy listener). But 192.168.1.x clients send to
-//   10.0.20.203, not the WAN IP, so those rules don't match.
-//
-//   This script adds 4 NAT rules that match dst=10.0.20.203 on mail ports
-//   and redirect them to 10.0.20.1 — same target as the public-Internet path.
-//   Roundcube traffic to :443 stays on Traefik (.203) untouched.
-//
-// USAGE (on pfSense host, via SSH as admin)
-//   scp infra/scripts/pfsense-nat-mail-lan-redirect.php admin@10.0.20.1:/tmp/
-//   ssh admin@10.0.20.1 'php /tmp/pfsense-nat-mail-lan-redirect.php'
-//
-// IDEMPOTENT — removes prior copies of our rules (by descr prefix) before
-// re-adding. Safe to re-run.
