# 端口映射模式
|
||||
|
||||
## 一、特点
|
||||
|
||||
1. 不需要tap/tun虚拟网卡
|
||||
2. 不需要管理员/root权限
|
||||
3. 使用端口映射来访问目标服务
|
||||
|
||||
## 二、作用
|
||||
|
||||
1. 和vnt互补，能简单快速构建网络
|
||||
2. 充当被访问端，外部依赖更少
|
||||
|
||||
## 三、使用方式
|
||||
|
||||
和vnt的使用方式一样，只是多了"--vnt-mapping"这个参数
|
||||
|
||||
### vn-link作为被访问端，不需要额外配置vnt-mapping
|
||||
|
||||
### vn-link访问vnt或者vn-link，需要加vnt-mapping
|
||||
|
||||
例如：
|
||||
|
||||
设备A 运行vnt(虚拟IP 10.26.0.A)，设备B 运行vn-link(虚拟IP 10.26.0.B)。
|
||||
|
||||
如果要用B访问A上的tcp 80端口，则在设备B上需要加--vnt-mapping "tcp:port1-10.26.0.A:80"
|
||||
|
||||
这个参数的作用是将B上的***本地端口port1***转发到设备A的地址10.26.0.A:
|
||||
80，此时在设备B上可以访问本地port1端口从而间接访问10.26.0.A:80
|
||||
|
||||
## 四、vn-link的子网代理
|
||||
|
||||
vn-link也支持点对网参数。 还是接着上面的例子
|
||||
|
||||
假设 设备C在设备A的子网下，C的子网IP为192.168.1.C，A的子网IP为192.168.1.A，要在设备B上访问C
|
||||
|
||||
则在B上加这些参数
|
||||
|
||||
- --vnt-mapping "tcp:port2-192.168.1.C:80" (将本地port2端口映射到C的80端口)
|
||||
- -i 192.168.1.0/24,10.26.0.A (将目标192.168.1.0/24的数据发送到10.26.0.A，也就是A节点)
|
||||
|
||||
在A上加参数
|
||||
|
||||
- -o 0.0.0.0/0 (允许所有流量转发)
|
||||
|
||||
***再次说明，vn-link作为被访问端时和vnt使用方式一致，vn-link作为访问端时需要加--vnt-mapping映射端口***
|
||||
|
||||
***vn-link是基于端口映射的使用模式，不会改变本地路由***
|
||||
|
||||
## 五、参数介绍
|
||||
|
||||
--vnt-mapping支持udp/tcp，例如 --vnt-mapping "tcp:port1-remoteIp:remotePort"
|
||||
|
||||
- 第一部分为协议，支持使用udp/tcp
|
||||
- 第二部分是本地端口，注意不要和本地服务的端口冲突
|
||||
- 第三部分是目标机器的地址，一般是目标虚拟IP地址，如果配置了点对网参数(-i和-o)则也可以是目标子网地址
