glider is a forward proxy with multiple protocols support, and also a dns/dhcp server with ipset management features(like dnsmasq).
we can set up local listeners as proxy servers, and forward requests to internet via forwarders.
```bash
|Forwarder ----------------->|
Listener --> | | Internet
|Forwarder --> Forwarder->...|
```
## Features
- Act as both proxy client and proxy server(protocol converter)
- Flexible proxy & protocol chains
- Load balancing with the following scheduling algorithm:
- rr: round robin
- ha: high availability
- lha: latency based high availability
- dh: destination hashing
- Rule & priority based forwarder choosing: [Config Examples](config/examples)
- DNS forwarding server:
- dns over proxy
- force upstream querying by tcp
- association rules between dns and forwarder choosing
- association rules between dns and ipset
- dns cache support
- custom dns record
- IPSet management (linux kernel version >= 2.6.32):
- add ip/cidrs from rule files on startup
- add resolved ips for domains from rule files by dns forwarding server
- Serve http and socks5 on the same port
- Periodical availability checking for forwarders
- Send requests from specific local ip/interface
- Services:
- dhcpd: a simple dhcp server that can run in failover mode

```bash
git clone https://github.com/nadoo/glider && cd glider
```
2. Customize features:
```bash
open `feature.go` & `feature_linux.go`, comment out the packages you don't need

## Proxy & Protocol Chains
In glider, you can easily chain several proxy servers or protocols together (click to see details)
- Chain proxy servers:
```bash
forward=http://1.1.1.1:80,socks5://2.2.2.2:1080,ss://method:[email protected]:8443@
```
- Chain protocols: https proxy (http over tls)
```bash
forward=tls://server.com:443,http://
```
- Chain protocols: vmess over ws over tls
```bash
forward=tls://server.com:443,ws://,vmess://5a146038-0b56-4e95-b1dc-5c6f5a32cd98@?alterID=2
```
- Chain protocols and servers:
``` bash
forward=socks5://1.1.1.1:1080,tls://server.com:443,vmess://5a146038-0b56-4e95-b1dc-5c6f5a32cd98@?alterID=2
```
- Chain protocols in listener: https proxy server
``` bash
listen=tls://:443?cert=crtFilePath&key=keyFilePath,http://
```
- Chain protocols in listener: http over smux over websocket proxy server
``` bash
listen=ws://:10000,smux://,http://
```
