 ## Development Plan
 
 * Log http request information in frps.
 * Direct reverse proxy, like haproxy.
 * Load balance to different service in frpc.
-* Frpc can directly be a webserver for static files.
-* P2p communicate by making udp hole to penetrate NAT.
 * kubernetes ingress support.

+### 范围端口映射
+
+在 frpc 的配置文件中可以指定映射多个端口，目前只支持 tcp 和 udp 的类型。
+
+这一功能通过 `range:` 段落标记来实现，客户端会解析这个标记中的配置，将其拆分成多个 proxy，每一个 proxy 以数字为后缀命名。
+
+例如要映射本地 6000-6005, 6007 这6个端口，主要配置如下：
+
+```ini
+# frpc.ini
+[range:test_tcp]
+type = tcp
+local_ip = 127.0.0.1
+local_port = 6000-6006,6007
+remote_port = 6000-6006,6007
+```
+
+实际连接成功后会创建 6 个 proxy，命名为 `test_tcp_0, test_tcp_1 ... test_tcp_5`。
+
 ### 插件
 
 默认情况下，frpc 只会转发请求到本地 tcp 或 udp 端口。

-# Quick Start
-
-frp is easier to use compared with other similar projects.
-
-We will use two simple demo to demonstrate how to use frp.
-
-1. How to create a connection to **server A**'s **ssh port** by **server B** with **public IP address** x.x.x.x(replace to the real IP address of your server).
-2. How to visit web service in **server A**'s **8000 port** and **8001 port** by **web01.yourdomain.com** and **web02.yourdomain.com** through **server B** with public ID address.
-
-### Download SourceCode
-
-`go get github.com/fatedier/frp` is recommended, then the code will be copied to the directory `$GOPATH/src/github.com/fatedier/frp`.
-
-Or you can use `git clone https://github.com/fatedier/frp.git $GOPATH/src/github.com/fatedier/frp`.
-
-If you want to try it quickly, download the compiled program and configuration files from [https://github.com/fatedier/frp/releases](https://github.com/fatedier/frp/releases).
-
-### Compile
-
-Enter the root directory and execute `make`, then wait until finished.
-
-**bin** include all executable programs when **conf** include corresponding configuration files.
-
-### Pre-requirement
-
-* Go environment. Version of go >= 1.4.
-* Godep (if not exist, `go get` will be executed to download godep when compiling)
-
-### Deploy
-
-1. Move `./bin/frps` and `./conf/frps.ini` to any directory of **server B**.
-2. Move `./bin/frpc` and `./conf/frpc.ini` to any directory of **server A**.
-3. Modify all configuration files, details in next paragraph.
-4. Execute `nohup ./frps &` or `nohup ./frps -c ./frps.ini &` in **server B**.
-5. Execute `nohup ./frpc &` or `nohup ./frpc -c ./frpc.ini &` in **server A**.
-6. Use `ssh -oPort=6000 {user}@x.x.x.x` to test if frp is work(replace {user} to real username in **server A**), or visit custom domains by browser.

-## Tcp port forwarding
-
-### Configuration files
-
-#### frps.ini
-
-```ini
-[common]
-bind_addr = 0.0.0.0
-# for accept connections from frpc
-bind_port = 7000
-log_file = ./frps.log

-
-## Http port forwarding and Custom domains binding
-
-If you only want to forward port one by one, you just need refer to [Tcp port forwarding](/doc/quick_start_en.md#Tcp-port-forwarding).If you want to visit different web pages deployed in different web servers by **server B**'s **80 port**, you should specify the type as **http**.
-
-You also need to resolve your **A record** of your custom domain to [server_addr], or resolve your **CNAME record** to [server_addr] if [server_addr] is a domain.
-
-After that, you can visit your web pages in local server by custom domains.
-
-### Configuration files
-
-#### frps.ini
-
-```ini
-[common]
-bind_addr = 0.0.0.0
-bind_port = 7000
-# if you want to support vhost, specify one port for http services

-# frp 使用文档
-
-相比于其他项目而言 frp 更易于部署和使用，这里我们用两个简单的示例来演示 frp 的使用过程。
-
-1. 如何通过一台拥有公网IP地址的**服务器B**，访问处于公司内部网络环境中的**服务器A**的**ssh**端口，**服务器B**的IP地址为 x.x.x.x（测试时替换为真实的IP地址）。
-2. 如何利用一台拥有公网IP地址的**服务器B**，使通过 **web01.yourdomain.com** 可以访问内网环境中**服务器A**上**8000端口**的web服务，**web02.yourdomain.com** 可以访问**服务器A**上**8001端口**的web服务。
-
-### 下载源码
-
-推荐直接使用 `go get github.com/fatedier/frp` 下载源代码安装，执行命令后代码将会拷贝到 `$GOPATH/src/github.com/fatedier/frp` 目录下。
-
-或者可以使用 `git clone https://github.com/fatedier/frp.git $GOPATH/src/github.com/fatedier/frp` 拷贝到相应目录下。
-
-如果您想快速进行测试，也可以根据您服务器的操作系统及架构直接下载编译好的程序及示例配置文件，[https://github.com/fatedier/frp/releases](https://github.com/fatedier/frp/releases)。
-
-### 编译
-
-进入下载后的源码根目录，执行 `make` 命令，等待编译完成。
-
-编译完成后， **bin** 目录下是编译好的可执行文件，**conf** 目录下是示例配置文件。
-
-### 依赖
-
-* go 1.4 以上版本
-* godep （如果检查不存在，编译时会通过 `go get` 命令安装）
-
-### 部署
-
-1. 将 ./bin/frps 和 ./conf/frps.ini 拷贝至**服务器B**任意目录。
-2. 将 ./bin/frpc 和 ./conf/frpc.ini 拷贝至**服务器A**任意目录。
-3. 根据要实现的功能修改两边的配置文件，详细内容见后续章节说明。
-4. 在服务器B执行 `nohup ./frps &` 或者 `nohup ./frps -c ./frps.ini &`。
-5. 在服务器A执行 `nohup ./frpc &` 或者 `nohup ./frpc -c ./frpc.ini &`。
-6. 通过 `ssh -oPort=6000 {user}@x.x.x.x` 测试是否能够成功连接**服务器A**（{user}替换为**服务器A**上存在的真实用户），或通过浏览器访问自定义域名验证 http 服务是否转发成功。
-
-## tcp 端口转发
-
-转发 tcp 端口需要按照需求修改 frps 和 frpc 的配置文件。
-
-### 配置文件
-
-#### frps.ini
-
-```ini
-[common]
-bind_addr = 0.0.0.0
-# 用于接收 frpc 连接的端口
-bind_port = 7000
-log_file = ./frps.log
-log_level = info
-
-# ssh 为代理的自定义名称，可以有多个，不能重复，和frpc中名称对应
-[ssh]
-auth_token = 123 
-bind_addr = 0.0.0.0
-# 最后将通过此端口访问后端服务
-listen_port = 6000
-```
-
-#### frpc.ini
-
-```ini
-[common]
-# frps 所在服务器绑定的IP地址
-server_addr = x.x.x.x
-server_port = 7000
-log_file = ./frpc.log
-log_level = info
-# 用于身份验证
-auth_token = 123 
-
-# ssh 需要和 frps.ini 中配置一致
-[ssh]
-# 需要转发的本地端口
-local_port = 22
-# 启用加密，frpc与frps之间通信加密，默认为 false
-use_encryption = true
-```
-
-## http 端口转发，自定义域名绑定
-
-如果只需要一对一的转发，例如**服务器B**的**80端口**转发**服务器A**的**8000端口**，则只需要配置 [tcp 端口转发](/doc/quick_start_zh.md#tcp-端口转发) 即可，如果需要使**服务器B**的**80端口**可以转发至**多个**web服务端口，则需要指定代理的类型为 http，并且在 frps 的配置文件中配置用于提供 http 转发服务的端口。
-
-按照如下的内容修改配置文件后，需要将自定义域名的 **A 记录**解析到 [server_addr]，如果 [server_addr] 是域名也可以将自定义域名的 **CNAME 记录**解析到 [server_addr]。
-
-之后就可以通过自定义域名访问到本地的多个 web 服务。
-
-### 配置文件
-
-#### frps.ini
-
-```ini
-[common]
-bind_addr = 0.0.0.0
-bind_port = 7000
-# 如果需要支持http类型的代理则需要指定一个端口
-vhost_http_port = 80
-log_file = ./frps.log
-log_level = info
-
-[web01]
-# type 默认为 tcp，这里需要特别指定为 http
-type = http
-auth_token = 123
-# 自定义域名绑定，如果需要同时绑定多个以英文逗号分隔
-custom_domains = web01.yourdomain.com
-
-[web02]
-type = http
-auth_token = 123
-custom_domains = web02.yourdomain.com
-```
-
-#### frpc.ini
-
-```ini
-[common]
-server_addr = x.x.x.x
-server_port = 7000
-log_file = ./frpc.log
-log_level = info
-auth_token = 123

-
-Go-spew implements a deep pretty printer for Go data structures to aid in
-debugging.  A comprehensive suite of tests with 100% test coverage is provided
-to ensure proper functionality.  See `test_coverage.txt` for the gocov coverage
-report.  Go-spew is licensed under the liberal ISC license, so it may be used in
-open source or commercial projects.
-
-If you're interested in reading about how this package came to life and some
-of the challenges involved in providing a deep pretty printer, there is a blog
-post about it
-[here](https://web.archive.org/web/20160304013555/https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).

-## Documentation
-
-[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)]
-(http://godoc.org/github.com/davecgh/go-spew/spew)
-
-Full `go doc` style documentation for the project can be viewed online without
-installing this package by using the excellent GoDoc site here:
-http://godoc.org/github.com/davecgh/go-spew/spew
-
-You can also view the documentation locally once the package is installed with
-the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
-http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
-
-## Installation
-
-```bash
-$ go get -u github.com/davecgh/go-spew/spew
-```
-
-## Quick Start
-
-Add this import line to the file you're working in:
-
-```Go
-import "github.com/davecgh/go-spew/spew"
-```
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
-
-```Go
-spew.Dump(myVar1, myVar2, ...)
-spew.Fdump(someWriter, myVar1, myVar2, ...)
-str := spew.Sdump(myVar1, myVar2, ...)
-```
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
-compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
-and pointer addresses): 
-
-```Go
-spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-```
-
-## Debugging a Web Application Example
-
-Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
-
-```Go
-package main
-
-import (
-    "fmt"
-    "html"
-    "net/http"
-
-    "github.com/davecgh/go-spew/spew"
-)
-
-func handler(w http.ResponseWriter, r *http.Request) {
-    w.Header().Set("Content-Type", "text/html")
-    fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
-    fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
-}
-
-func main() {
-    http.HandleFunc("/", handler)
-    http.ListenAndServe(":8080", nil)
-}
-```
-
-## Sample Dump Output
-
-```
-(main.Foo) {
- unexportedField: (*main.Bar)(0xf84002e210)({
-  flag: (main.Flag) flagTwo,
-  data: (uintptr) <nil>
- }),
- ExportedField: (map[interface {}]interface {}) {
-  (string) "one": (bool) true
- }
-}
-([]uint8) {
- 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
- 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
- 00000020  31 32                                             |12|
-}
-```
-
-## Sample Formatter Output
-
-Double pointer to a uint8:
-```
-	  %v: <**>5
-	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
-	 %#v: (**uint8)5
-	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-```
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
-```
-	  %v: <*>{1 <*><shown>}
-	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
-	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
-	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
-```
-
-## Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type. For
-convenience, all of the top-level functions use a global state available via the
-spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions. This allows concurrent configuration
-options. See the ConfigState documentation for more details.
-
-```
-* Indent
-	String to use for each indentation level for Dump functions.
-	It is a single space by default.  A popular alternative is "\t".
-
-* MaxDepth
-	Maximum number of levels to descend into nested data structures.
-	There is no limit by default.
-
-* DisableMethods
-	Disables invocation of error and Stringer interface methods.
-	Method invocation is enabled by default.
-
-* DisablePointerMethods
-	Disables invocation of error and Stringer interface methods on types
-	which only accept pointer receivers from non-pointer variables.  This option
-	relies on access to the unsafe package, so it will not have any effect when
-	running in environments without access to the unsafe package such as Google
-	App Engine or with the "safe" build tag specified.
-	Pointer method invocation is enabled by default.
-
-* DisablePointerAddresses
-	DisablePointerAddresses specifies whether to disable the printing of
-	pointer addresses. This is useful when diffing data structures in tests.
-
-* DisableCapacities
-	DisableCapacities specifies whether to disable the printing of capacities
-	for arrays, slices, maps and channels. This is useful when diffing data
-	structures in tests.
-
-* ContinueOnMethod
-	Enables recursion into types after invoking error and Stringer interface
-	methods. Recursion after method invocation is disabled by default.
-
-* SortKeys
-	Specifies map keys should be sorted before being printed. Use
-	this to have a more deterministic, diffable output.  Note that
-	only native types (bool, int, uint, floats, uintptr and string)
-	and types which implement error or Stringer interfaces are supported,
-	with other types sorted according to the reflect.Value.String() output
-	which guarantees display stability.  Natural map order is used by
-	default.
-
-* SpewKeys
-	SpewKeys specifies that, as a last resort attempt, map keys should be
-	spewed to strings and sorted by those strings.  This is only considered
-	if SortKeys is true.
-
-```
-
-## Unsafe Package Dependency
-
-This package relies on the unsafe package to perform some of the more advanced
-features, however it also supports a "limited" mode which allows it to work in
-environments where the unsafe package is not available.  By default, it will
-operate in this mode on Google App Engine and when compiled with GopherJS.  The
-"safe" build tag may also be specified to force the package to build without
-using the unsafe package.
