## Features

- Local HTTP/HTTPS/SOCKS server with authentication support
- VMess, Shadowsocks, Trojan, Snell protocol support for remote connections
- Built-in DNS server that aims to minimize DNS pollution attack impact, supports DoH/DoT upstream and fake IP.
- Rules based off domains, GEOIP, IPCIDR or Process to forward packets to different nodes
- Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node based off latency
- Remote providers, allowing users to get node lists remotely instead of hardcoding in config
- Netfilter TCP redirecting. Deploy Clash on your Internet gateway with `iptables`.
- Comprehensive HTTP RESTful API controller

## Getting Started
Documentations are now moved to [GitHub Wiki](https://github.com/Dreamacro/clash/wiki).

## Advanced usage for this branch

### DNS configuration

Support `geosite` with `fallback-filter`.

Restore `Redir remote resolution`.

Support resolve ip with a `Proxy Tunnel`.

```yaml
proxy-groups:

  - name: DNS
    type: url-test
    use:
      - HK
    url: http://cp.cloudflare.com
    interval: 180
    lazy: true
```
```yaml
dns:
  enable: true
  use-hosts: true
  ipv6: false
  enhanced-mode: redir-host
  fake-ip-range: 198.18.0.1/16
  listen: 127.0.0.1:6868
  default-nameserver:
    - 119.29.29.29
    - 114.114.114.114
  nameserver:
    - https://doh.pub/dns-query
    - tls://223.5.5.5:853
  fallback:
    - 'https://1.0.0.1/dns-query#DNS'  # append the proxy adapter name or group name to the end of DNS URL with '#' prefix.
    - 'tls://8.8.4.4:853#DNS'
  fallback-filter:
    geoip: false
    geosite:
      - gfw  # `geosite` filter only use fallback server to resolve ip, prevent DNS leaks to unsafe DNS providers.
    domain:
      - +.example.com
    ipcidr:
      - 0.0.0.0/32
```

### TUN configuration

Supports macOS, Linux and Windows.

Built-in [Wintun](https://www.wintun.net) driver.

```yaml
# Enable the TUN listener
tun:
  enable: true
  stack: gvisor #  only gvisor
  dns-hijack: 
    - 0.0.0.0:53 # additional dns server listen on TUN
  auto-route: true # auto set global route
```
### Rules configuration
- Support rule `GEOSITE`.
- Support rule-providers `RULE-SET`.
- Support `multiport` condition for rule `SRC-PORT` and `DST-PORT`.
- Support `network` condition for all rules.
- Support source IPCIDR condition for all rules, just append to the end.
- The `GEOSITE` databases via https://github.com/Loyalsoldier/v2ray-rules-dat.
```yaml
rules:

  # network(tcp/udp) condition for all rules
  - DOMAIN-SUFFIX,bilibili.com,DIRECT,tcp
  - DOMAIN-SUFFIX,bilibili.com,REJECT,udp
    
  # multiport condition for rules SRC-PORT and DST-PORT
  - DST-PORT,123/136/137-139,DIRECT,udp
  
  # rule GEOSITE
  - GEOSITE,category-ads-all,REJECT
  - GEOSITE,icloud@cn,DIRECT
  - GEOSITE,apple@cn,DIRECT
  - GEOSITE,apple-cn,DIRECT
  - GEOSITE,microsoft@cn,DIRECT
  - GEOSITE,facebook,PROXY
  - GEOSITE,youtube,PROXY
  - GEOSITE,geolocation-cn,DIRECT
  - GEOSITE,geolocation-!cn,PROXY
    
  # source IPCIDR condition for all rules in gateway proxy
  #- GEOSITE,geolocation-!cn,REJECT,192.168.1.88/32,192.168.1.99/32

  - GEOIP,telegram,PROXY,no-resolve
  - GEOIP,private,DIRECT,no-resolve
  - GEOIP,cn,DIRECT
  
  - MATCH,PROXY
```


### Proxies configuration

Active health detection `urltest / fallback` (based on tcp handshake, multiple failures within a limited time will actively trigger health detection to use the node)

Support `Policy Group Filter`

```yaml
proxy-groups:

  - name: 🚀 HK Group
    type: select
    use:
      - ALL
    filter: 'HK'

  - name: 🚀 US Group
    type: select
    use:
      - ALL
    filter: 'US'

proxy-providers:
  ALL:
    type: http
    url: "xxxxx"
    interval: 3600
    path: "xxxxx"
    health-check:
      enable: true
      interval: 600
      url: http://www.gstatic.com/generate_204

```



Support outbound transport protocol `VLESS`.

The XTLS only support TCP transport by the XRAY-CORE.
```yaml
proxies:
  - name: "vless-tcp"
    type: vless
    server: server
    port: 443
    uuid: uuid
    network: tcp
    servername: example.com # AKA SNI
    # flow: xtls-rprx-direct # xtls-rprx-origin  # enable XTLS
    # skip-cert-verify: true
    
  - name: "vless-ws"
    type: vless
    server: server
    port: 443
    uuid: uuid
    udp: true
    network: ws
    servername: example.com # priority over wss host
    # skip-cert-verify: true
    ws-path: /path
    ws-headers:
      Host: example.com
```

### IPTABLES auto-configuration
Only work on Linux OS who support `iptables`, Clash will auto-configuration iptables for tproxy listener when `tproxy-port` value isn't zero.

If `TPROXY` is enabled, the `TUN` must be disabled.
```yaml
# Enable the TPROXY listener
tproxy-port: 9898
# Disable the TUN listener
tun:
  enable: false
```
Create user given name `Clash.Meta`.

Run Meta Kennel by user `Clash.Meta` as a daemon.

Create the systemd configuration file at /etc/systemd/system/clash.service:

```
[Unit]
Description=Clash.Meta Daemon, Another Clash Kennel.
After=network.target

[Service]
Type=simple
User=Clash.Meta
Group=Clash.Meta
CapabilityBoundingSet=cap_net_admin
AmbientCapabilities=cap_net_admin
Restart=always
ExecStart=/usr/local/bin/Clash.Meta -d /etc/Clash.Meta

[Install]
WantedBy=multi-user.target
```
Launch clashd on system startup with:
```shell
$ systemctl enable Clash.Meta
```
Launch clashd immediately with:

```shell
$ systemctl start Clash.Meta
```

### Display Process name

Clash add field `Process` to `Metadata` and prepare to get process name for Restful API `GET /connections`.

To display process name in GUI please use [Dashboard For Meta](https://github.com/Clash-Mini/Dashboard).
