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.

|

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 before version 1.x.**
|
||||
|
||||
## Quick Start
|
||||
|
||||
Read the [QuickStart](/doc/quick_start_en.md)
|
||||
|
||||
[Tcp port forwarding](/doc/quick_start_en.md#tcp-port-forwarding)
|
||||
|
||||
[Http port forwarding and Custom domain binding](/doc/quick_start_en.md#http-port-forwarding-and-custom-domains-binding)
|
||||
**We may change any protocol and can't promise backward compatible.Please note the release log when upgrading.**
|
||||
|
||||
## Architecture
|
||||
|
||||
|
||||
|
||||
## 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.
