Build Status Go Report Card GitHub tag GitHub release

glider is a forward proxy with multiple protocols support, and also a dns forwarding server with ipset management features(like dnsmasq).

we can set up local listeners as proxy servers, and forward requests to internet via forwarders.

                |Forwarder ----------------->|         
   Listener --> |                            | Internet
                |Forwarder --> Forwarder->...| 

Features

Listen (local proxy server):

  • Socks5 proxy(tcp&udp)
  • Http proxy(tcp)
  • SS proxy(tcp&udp)
  • Linux transparent proxy(iptables redirect)
  • TCP tunnel
  • UDP tunnel
  • UDP over TCP tunnel
  • DNS Tunnel(udp2tcp)

Forward (local proxy client/upstream proxy server):

  • Socks5 proxy(tcp&udp)
  • Http proxy(tcp)
  • SS proxy(tcp&udp&uot)
  • SSR proxy(tcp)
  • VMess proxy(tcp)
  • TLS, use it together with above proxy protocols(tcp)

DNS Forwarding Server (udp2tcp):

  • Listen on UDP and forward dns requests to remote dns server in TCP via forwarders
  • Specify different upstream dns server based on destinations(in rule file)
  • Tunnel mode: forward to a fixed upstream dns server
  • Add resolved IPs to proxy rules
  • Add resolved IPs to ipset

IPSet Management:

  • Add ip/cidrs from rule files on startup
  • Add resolved ips for domains from rule files by dns forwarding server

General:

  • Http and socks5 on the same port
  • Forward chain
  • HA or RR strategy for multiple forwarders
  • Periodical proxy checking
  • Rule proxy based on destinations: Config Examples

TODO:

  • Transparent UDP proxy (iptables tproxy)
  • DNS Cache
  • Performance tuning
  • TUN/TAP device support
  • IPv6 support
  • SSH tunnel support

Available Schemes:
  mixed: serve as a http/socks5 proxy on the same port. (default)
  ss: ss proxy
  socks5: socks5 proxy
  http: http proxy
  ssr: ssr proxy
  vmess: vmess proxy
  redir: redirect proxy. (used on linux as a transparent proxy with iptables redirect rules)
  tcptun: tcp tunnel
  udptun: udp tunnel
  uottun: udp over tcp tunnel
  dnstun: listen on udp port and forward all dns requests to remote dns server via forwarders(tcp)

Available schemes for different modes:
  listen: mixed ss socks5 http redir tcptun udptun uottun dnstun
  forward: ss socks5 http ssr vmess

SS scheme:
  ss://method:pass@host:port

Available methods for ss:
  AEAD_AES_128_GCM AEAD_AES_192_GCM AEAD_AES_256_GCM AEAD_CHACHA20_POLY1305 AES-128-CFB AES-128-CTR AES-192-CFB AES-192-CTR AES-256-CFB AES-256-CTR CHACHA20-IETF XCHACHA20
  NOTE: chacha20-ietf-poly1305 = AEAD_CHACHA20_POLY1305

SSR scheme:
  ssr://method:pass@host:port?protocol=xxx&protocol_param=yyy&obfs=zzz&obfs_param=xyz

VMess scheme:
  vmess://uuid[:method]@host:port?alterID=num

Available methods for vmess:
  NONE, (will add aes-128-gcm and chacha20-poly1305 later)

Available forward strategies:
  rr: Round Robin mode
  ha: High Availability mode

Config file format(see `glider.conf.example` as an example):
  # COMMENT LINE
  KEY=VALUE
  KEY=VALUE
  # KEY equals to command line flag name: listen forward strategy...

Examples:
  glider -config glider.conf
    -run glider with specified config file.

  glider -config glider.conf -rulefile office.rule -rulefile home.rule
    -run glider with specified global config file and rule config files.
