## What is frp?
frp is a fast reverse proxy to help you expose a local server behind a NAT or firewall to the internet.Now, it supports tcp, http and https protocol when requests can be forwarded by domains to backward web services.

## What can I do with frp?
* Expose any http and https service behind a NAT or firewall to the internet by a server with public IP address(Name-based Virtual Host Support).
* Expose any tcp service behind a NAT or firewall to the internet by a server with public IP address.
* Inspect all http requests/responses that are transmitted over the tunnel(future).
## Status
frp is under development and you can try it with latest release version.Master branch for releasing stable version when dev branch for developing.
**We may change any protocol and can't promise backward compatible.Please note the release log when upgrading.**
## Architecture
![architecture](/doc/pic/architecture.png)
## Example Usage
First, download the latest version programs from [Release](https://github.com/fatedier/frp/releases) page according to your os and arch.
Put **frps** and **frps.ini** to your server with public IP.
Put **frpc** and **frpc.ini** to your server in LAN.
### Communicate with your computer in LAN by SSH
1. Modify frps.ini, configure a reverse proxy named [ssh]:
```ini
# frps.ini
[common]
bind_port = 7000
[ssh]
listen_port = 6000
auth_token = 123
```
2. Start frps:
`./frps -c ./frps.ini`
3. Modify frpc.ini, set remote frps's server IP as x.x.x.x:
```ini
# frpc.ini
[common]
server_addr = x.x.x.x
server_port = 7000
auth_token = 123
[ssh]
local_port = 22
```
4. Start frpc:
`./frpc -c ./frpc.ini`
5. Connect to server in LAN by ssh assuming that username is test:
`ssh -oPort=6000 test@x.x.x.x`
### Visit your web service in LAN by specific domain
Sometimes we need to expose a local web service behind a NAT network to others for testing with your own domain and unfortunately we can't resolve a domain to a local ip.
Howerver, we can expose a http or https service using frp.
1. Modify frps.ini, configure a http reverse proxy named [web] and set http port as 8080, custom domain as www.yourdomain.com:
```ini
# frps.ini
[common]
bind_port = 7000
vhost_http_port = 8080
[web]
type = http
custom_domains = www.yourdomain.com
auth_token = 123
```
2. Start frps:
`./frps -c ./frps.ini`
3. Modify frpc.ini and set remote frps server's IP as x.x.x.x. The local_port is the port of your web service:
```ini
# frpc.ini
[common]
server_addr = x.x.x.x
server_port = 7000
auth_token = 123
[web]
type = http
local_port = 80
```
4. Start frpc:
`./frpc -c ./frpc.ini`
5. Resolve A record of www.yourdomain.com to x.x.x.x or CNAME record to your origin domain.
6. Now your can visit your local web service from url `http://www.yourdomain.com:8080`.
## Features
### Authentication
`auth_token` is used in frps.ini for authentication when frpc login in and you should configure it for each proxy.
Client should set a global `auth_token` equals to frps.ini.
Note that time duration bewtween frpc and frps shouldn't exceed 15 minutes because timestamp is used for authentication.
### Encryption and Compression
Defalut value is false, you could decide if the proxy should use encryption or compression whether the type is:
```ini
# frpc.ini
[ssh]
type = tcp
listen_port = 6000
auth_token = 123
use_encryption = true
use_gzip = true
```
### Reload configures without frps stopped
If your want to add a new reverse proxy and avoid restarting frps, you can use this feature.
1. `dashboard_port` should be set in frps.ini:
```ini
# frps.ini
[common]
bind_port = 7000
dashboard_port = 7500
```
2. Start frps:
`./frps -c ./frps.ini`
3. Modify frps.ini to add a new proxy [new_ssh]:
```ini
# frps.ini
[common]
bind_port = 7000
dashboard_port = 7500
[new_ssh]
listen_port = 6001
auth_token = 123
```
4. Execute `reload` command:
`./frps -c ./frps.ini --reload`
5. Start frpc and [new_ssh] is available now.
### Privilege Mode
Privilege mode is used for who don't want to do operations in frps everytime adding a new proxy.
All proxies's configures are set in frpc.ini when privilege mode is enabled.
1. Enable privilege mode and set `privilege_token`.Client with the same `privilege_token` can create proxy automaticly:
```ini
# frps.ini
[common]
bind_port = 7000
privilege_mode = true
privilege_token = 1234
```
2. Start frps:
`./frps -c ./frps.ini`
3. Enable privilege mode for proxy [ssh]:
```ini
# frpc.ini
[common]
server_addr = x.x.x.x
server_port = 7000
privilege_token = 1234
[ssh]
privilege_mode = true
local_port = 22
remote_port = 6000
```
4. Start frpc:
`./frpc -c ./frpc.ini`
5. Connect to server in LAN by ssh assuming that username is test:
`ssh -oPort=6000 test@x.x.x.x`
## Development Plan
* Dashboard page.
* Statistics and prestentation of traffic and connection info, etc.
* Support udp protocol.
* Connection pool.
* White list for opening specific ports in privilege mode.
* Support wildcard domain name.
* Url router.
* Load balance to different service in frpc.
* Debug mode for frpc, prestent proxy status in terminal.
* Inspect all http requests/responses that are transmitted over the tunnel.
* P2p communicate by make udp hole to penetrate NAT.
