Mehrere zusammenhängende Fehler beim Import der NAT-Rules von der
alten EdgeGuard-Box gefunden + behoben:
1. nft-Template: NAT-Rules landeten als Comment (gleicher
Whitespace-Trimmer-Bug wie bei den Operator-Rules vor zwei
commits). Fix: Body auf eigener Zeile via {{""}}-Padding.
2. nft-Syntax-Reihenfolge: emittierte 'tcp ip daddr X dport Y' →
parser-Fehler. Korrekt ist L3-match (ip saddr/daddr) zuerst,
dann L4 (tcp/udp dport). Reihenfolge in der dnat-Zeile
getauscht.
3. eth0 als Iface-Row hinzugefügt (Type ethernet, role wan) damit
der zone→iface-Lookup für 'wan' tatsächlich auf das Linux-Iface
trifft. Vorher war nur 'WAN'-bridge in der DB, das im Kernel
nicht existiert → iifname-match griff nicht.
4. forward-chain: ct status dnat accept (DNAT-Pakete dürfen
forwarden) + Auto-Forward pro SNAT/masquerade-Rule für die
Origin-Pakete (return geht via established,related).
5. postrouting_nat: ct status dnat masquerade als Hairpin-Catch-All
— sonst antwortet das DNAT-Ziel via seinem default-GW (oft
nicht zur EdgeGuard-Box) → SYN_SENT + UNREPLIED. Trade-off:
Backend sieht Box-IP statt client-IP.
6. Sysctl-Profil /etc/sysctl.d/99-edgeguard.conf bei jedem Install:
- Forwarding (ip_forward + ipv6 forwarding) — Voraussetzung für
ALLES NAT/DNAT/Masquerade.
- Conntrack-Buckets + max=524288 (Edge-Box trackt viele
parallele Sessions).
- HAProxy-Tuning (somaxconn 64k, rmem/wmem 16M, keepalive,
tcp_tw_reuse, ip_local_port_range).
- BBR + fq als modernes Congestion-Control + Queueing.
- Anti-DoS: tcp_syncookies, log_martians, kptr_restrict.
Verified end-to-end:
