+# vds haproxy + wireguard + ipvs
+
+L4 балансировщик и шлюз для распределения tcp/udp сервисов во внутреннюю сеть через wireguard с использованием haproxy, ipvs и nftables.
+
+## Архитектура
+
+- Вход: публичные порты vds
+- tcp → haproxy
+- udp / спец. tcp → nftables (`fwmark`) → `ipvs`
+- Транспорт → wireguard (`wg0`)
+- NAT → netmap (1:1 подсети)
+
+## Компоненты
+
+### haproxy (tcp)
+
+Работает в `mode tcp`, проксирует с поддержкой `proxy-protocol`:
+
+| Порт | Сервис | Backend |
+| --- | --- | --- |
+| 80 | HTTP | 10.x.102.3:81 |
+| 443 | HTTPS | 10.x.102.3:444 |
+| 22 | Gitea SSH  | 10.x.103.3:22 |
+| 24444 | MCSManager | 10.x.103.3:24445 |
+
+### xmpp (prosody)
+
+Прямой tcp проброс:
+
+| Порт | Сервис |
+| --- | --- |
+| 5222, 5223 | client |
+| 5269 | server |
+| 5000 | proxy65 |
+| 5270 | components |
+| 5280 | BOSH |
+
+---
+
+## wireguard
+
+- Интерфейс: `wg0`
+- Подсеть: `10.x.200.0/24`
+
+#### Функции:
+
+- транспорт между узлами
+- запуск `nftables` и `ipvs`
+- включение `ip_forward` и `conntrack`
+
+## ipvs (fwmark)
+
+Балансировка по меткам:
+
+| Марка | Сервис | Backend |
+| --- | --- | --- |
+| 10 | coturn | 10.x.103.10 |
+| 20 | minecraft | 10.x.104.3 |
+| 30 | steam/valheim | 10.x.104.4 |
+| 40 | rustdesk | 10.x.200.1 |
+
+Алгоритм: `rr`
+
+
+## nftables
+
+### prerouting
+
+Классификация трафика:
+
+- wireguard (51820) → accept
+- coturn → mark 10
+- minecraft → mark 20
+- steam / valheim → mark 30
+- rustdesk → mark 40
+- nat (postrouting)
+
+1:1 netmap через **wg0**:
+
+```bash
+10.x.0.0/24    → 10.x.100.0/24
+10.x.1.0/24    → 10.x.101.0/24
+10.x.2.0/24   → 10.x.102.0/24
+10.x.3.0/24   → 10.x.103.0/24
+10.x.4.0/24   → 10.x.104.0/24
+10.x.5.0/24   → 10.x.105.0/24
+192.x.x.0/24 → 10.x.200.0/24
+```
+
+## Поток трафика
+1. Клиент → vds
+2. haproxy (tcp) или nftables (udp/marked tcp)
+3. Проставление `fwmark`
+4. ipvs → выбор backend
+5. SNAT (netmap) → wireguard
+6. Доставка в целевую подсеть
+
+## Цикл жизни
+
+### PostUp
+- загрузка модулей: `ip_vs`, `nf_conntrack`
+- включение `ip_forward`
+- применение `nftables`
+- настройка `ipvs` (`fwmark rules`)
+
+### PostDown
+- очистка `ipvs`
+- удаление таблицы `nftables`
+
+## Особенности
+- Используется `proxy-protocol` для реального ip
+- udp балансируется через `ipvs`
+- Сегментация через netmap (жёсткое соответствие подсетей)
+- Все сервисы заходят через одну точку (vds)
+
+## Зависимости
+
+```bash
+apt update
+apt install ipvsadm ufw haproxy wireguard-tools
+```
