BlindMaster24 43e64993fc fix(amneziawg): refuse a row's own relay port and keep a disabled row's slot reserved (#6544)
* fix(amneziawg): refuse a WireGuard port that is the row's own relay port

All three relay checks filter themselves out of the candidates with id !=
ignoreId, so nothing ever compared an AmneziaWG row's own WireGuard listen port
with the relay port its own id derives. Saving a row on that exact port left the
embedded device (UDP on the inbound's listen address, amneziawgnet/device.go:137)
and its injected relay (TCP and UDP on 127.0.0.1, amneziawgnet/relay.go:47-61)
bound to the same UDP port, so whichever loses the race dies -- and when the
relay loses it, Xray refuses the whole config and takes every other protocol on
the host with it. The first AmneziaWG inbound on port 65101 was enough to reach
it: id 1 derives exactly that port.

The row now states the rule its three siblings do: it owns the slot its id
derives. A node-hosted row still keeps its own port, since it binds no relay on
this host.

TestAddInbound_AmneziawgRefusesItsOwnRelayPort and
TestUpdateInbound_AmneziawgRefusesItsOwnRelayPort fail without this -- both were
watched red first -- and pin the two separate call sites, AddInbound's post-Save
block and checkPortConflictTx's ignoreId > 0 block.

* fix(amneziawg): keep a disabled row's relay port reserved for port forwards

loadPortConflictContext filtered its query with enable = true, so a client's
ForwardedPorts spec could claim the relay port a disabled AmneziaWG row's id
derives. That row's relay appears with its first client -- a path that runs no
port check -- and when the relay then loses the loopback bind race to the
forward listener, Xray refuses the whole config instead of losing one forward
(#6542 review, arrived with #6540).

The context now loads every local row and gates only the ordinary-port compare on
enable, which is what a disabled row's own port is worth: free. Its relay slot is
not free, which is the rule #6540 already states for the other two guards.

TestCheckForwardedPortsConflict_DisabledAmneziawgRelayPortIsReserved fails
without this -- watched red first -- and passes with it, while
TestCheckForwardedPortsConflict_IgnoresDisabledInboundPort keeps proving that a
disabled inbound's own port stays available.

* fix(amneziawg): re-run the forward guard once a new row has its own ports

normalizeAmneziaWGSettings validates every client's ForwardedPorts before the row
is saved, and loadPortConflictContext then reads the database -- so the new
AmneziaWG row is never a candidate for itself. A client could forward exactly the
relay port the row's own id derives, or its own WireGuard listen port, and the
create was accepted: at runtime the panel's wildcard forward listener and Xray's
127.0.0.1 relay race for the same port, and a lost relay bind makes Xray refuse
the whole generated config (#6544 review, pre-existing).

The post-Save block is the only place the id is known, so it re-runs the guard
there. Both callers now share amneziaWGForwardedPortsConflict, so the collision
message lives in one place instead of two.

TestAddInbound_AmneziawgRefusesAClientForwardingItsOwnRelayPort fails without
this -- watched red first -- and passes with it.

* fix(amneziawg): stop blocking stored forward specs on a disabled row's slot

Round 2 flagged this PR's widening as the one MEDIUM it introduced, and the code
confirms it: UpdateInboundClient carries a stored ForwardedPorts spec forward for
a partial edit (client_inbound_apply.go:763-765) and re-validates it (:772 and
:909), so after an in-place upgrade an edit that never submitted the field -- a
bot enable/expiry toggle -- is refused over a slot the operator did not touch,
for a relay injectAmneziawgnetSocks does not emit while the row is disabled. The
inbound-save path re-validates every stored spec the same way.

The trade does not pay for itself: the slot this reserves is claimable only by a
spec an operator authors onto 65101-65535, while the cost lands on unrelated
operations. The precise fix -- refuse a newly claimed spec rather than a stored
one, and check the enable transition in SetInboundEnable, where the conflict is
actually created -- is larger than the hole, so the slot goes back to a
documented pre-existing item with its own follow-up.

The create-path re-run added in 80eb5712 is unaffected: it reads the settings
submitted in the same request, so it never refuses a stored value, and its test
still passes.

3x-ui

Release Build GO Version Downloads License Go Reference Documentation

3X-UI is an advanced, open-source web control panel for managing Xray-core servers. It provides a clean, multi-language interface for deploying, configuring, and monitoring a wide range of proxy and VPN protocols — from a single VPS to multi-node deployments.

Built as an enhanced fork of the original X-UI project, 3X-UI adds broader protocol support, improved stability, per-client traffic accounting, and many quality-of-life features.

Important

This project is intended for personal use only. Please do not use it for illegal purposes or in a production environment.

Features

  • Multi-protocol inbounds — VLESS, VMess, Trojan, Shadowsocks, WireGuard, AmneziaWG, TUIC v5, Hysteria2, MTProto, HTTP, SOCKS (Mixed), Dokodemo-door / Tunnel, and TUN.
  • Modern transports & security — TCP (Raw), mKCP, WebSocket, gRPC, HTTPUpgrade, and XHTTP, secured with TLS, XTLS, and REALITY.
  • AmneziaWG built in — DPI-resistant WireGuard runs inside the panel on a userspace network stack, with no kernel module, DKMS, or extra packages to install.
  • TUIC v5 sidecar — High-performance QUIC-based proxy with native UDP relay traffic metering, 0-RTT handshakes, and BBR congestion control.
  • MTProto proxies — per-client FakeTLS secrets, ad-tags, and quotas, applied live without dropping existing connections.
  • Fallbacks — serve multiple protocols on a single port (e.g. VLESS and Trojan on 443) using Xray's fallback support.
  • Per-client management — traffic quotas, expiry dates, IP limits with trusted-address exemptions, HWID device limits, scheduled renewal cycles, live online status, and one-click share links, QR codes, and subscriptions.
  • Traffic statistics — per inbound, per client, and per outbound, with reset controls.
  • Multi-node support — manage and scale across multiple servers from a single panel, including cloning inbounds onto other nodes.
  • Outbound & routing — WARP, NordVPN, PIA, custom routing rules, load balancers with balancer-to-balancer fallback, and outbound proxy chaining. Bundled geosite and geoip categories are browsable straight from the rule editor.
  • Built-in subscription server — raw, JSON, and Clash output, auto-selected from the client's User-Agent, plus custom page templates.
  • Telegram and Discord bots for remote monitoring and management.
  • RESTful API with scoped, optionally expiring tokens and an in-panel API reference.
  • Installable panel (PWA) — pin 3X-UI to a desktop or phone home screen.
  • Flexible storage — SQLite (default) or PostgreSQL.
  • 13 UI languages with dark and light themes.
  • Fail2ban integration for enforcing per-client IP limits.

Quick Start

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)

To install a specific version, append its tag (e.g. v3.7.0):

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) v3.7.0

To install the rolling dev build (latest per-commit pre-release from main, not a stable release), pass dev-latest:

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) dev-latest

During installation a random username, password, and access path are generated. After installation, run x-ui to open the management menu, where you can start/stop the service, view or reset your login credentials, manage SSL certificates, and more.

Every release asset is published with a .sha256 sum next to it. Both install.sh and the updater verify the archive against that sum and abort on a mismatch.

Unattended install

The installer also runs non-interactively for cloud-init. Set XUI_NONINTERACTIVE=1 (or pipe with no TTY) and it installs end-to-end with zero prompts, generating random credentials and writing them to /etc/x-ui/install-result.env. See deploy/ for:

Supported Platforms

Operating systems: Ubuntu, Debian, Armbian, Fedora, CentOS, RHEL, AlmaLinux, Rocky Linux, Oracle Linux, Amazon Linux, Virtuozzo, Arch, Manjaro, Parch, openSUSE (Tumbleweed / Leap), Alpine, and Windows.

Architectures: amd64 · 386 · arm64 (aarch64) · armv7 · armv6 · armv5 · s390x.

Database Options

3X-UI supports two backends, chosen during the install:

  • SQLite (default) — a single file at /etc/x-ui/x-ui.db. Zero setup, ideal for small and medium deployments.
  • PostgreSQL — recommended for high client counts or multi-node setups. The installer can install PostgreSQL locally for you, or accept a DSN to an existing server.

At runtime the backend is selected via environment variables (the installer writes these to /etc/default/x-ui for you):

XUI_DB_TYPE=postgres
XUI_DB_DSN=postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable

Migrating an existing SQLite install to PostgreSQL

x-ui migrate-db --dsn "postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable"
# then set XUI_DB_TYPE and XUI_DB_DSN in /etc/default/x-ui and restart:
systemctl restart x-ui

The source SQLite file is left untouched; remove it manually once you have verified the new backend.

Docker

The default docker compose up -d keeps using SQLite. To run with the bundled PostgreSQL service, uncomment the two XUI_DB_* env lines in docker-compose.yml and start with the profile:

docker compose --profile postgres up -d

The image bundles Fail2ban (enabled by default) to enforce per-client IP limits. Fail2ban bans offenders with iptables, which requires the NET_ADMIN capability. docker-compose.yml already grants it via cap_add; if you start the container with docker run instead, add the capabilities yourself, otherwise bans are logged but never applied:

docker run -d --cap-add=NET_ADMIN --cap-add=NET_RAW ... ghcr.io/mhsanaei/3x-ui
