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.

## 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)
|
|
|
|
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](config/examples)

TODO:
|
|
|
|
- [ ] Transparent UDP proxy (iptables tproxy)
|
|
- [ ] DNS Cache
|
|
- [ ] TUN/TAP device support
|
|
- [ ] Code refactoring: support proxy registering so it can be pluggable
|
|
- [ ] Conditional compilation so we can abandon needless proxy type and get a smaller binary size
|
|
- [ ] IPv6 support
|
|
- [ ] SSH tunnel support
|
