|
|

|
|
raspberry pi b+
|
|
eth0 192.168.1.10/24 192.168.1.2

## iptables 命令
|
|
|
|
参考自 http://man.linuxde.net/iptables
|
|
|
|
``` bash
|
|
iptables -t 表名 <-A/I/D/R> 规则链名 [规则号] <-i/o 网卡名> -p 协议名 <-s 源IP/源子网> --sport 源端口 <-d 目标IP/目标子网> --dport 目标端口 -j 动作
|
|
|
|
```
|
|
|
|
## 转发80端口到其他端口
|
|
|
|
``` bash
|
|
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 4000
|

## 设置静态ip
|
|
|
|
> sudo nano /etc/network/interfaces
|
|
|
|
``` bash
|
|
auto eth0
|
|
iface eth0 inet static
|
|
address 192.168.8.100
|
|
netmask 255.255.255.0
|
|
gateway 192.168.8.2
|
|
