# 用树莓派做路由器

## 网络配置

wlan0 连接公网，并将网络共享给有线网和wlan1

``` bash
auto eth0
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0


auto wlan0
iface wlan0 inet dhcp
wpa_conf /etc/wpa_supplicant/wpa_supplicant.conf


auto wlan1
iface wlan1 inet static
address 192.168.2.1
netmask 255.255.255.0
```

## 固定wlan名称

sudo nano /etc/udev/rules.d/10-network.rules

``` bash
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="MAC_address",name="wlan0"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="MAC_address",name="wlan1"
```

## 安装配饰DHCP服务

sudo apt install dnsmasq

nano /etc/dnsmasq.conf

``` bash
listen-address = 127.0.0.1, 192.168.1.1, 192.168.2.1
dhcp-range = 192.168.1.20, 192.168.1.200, 12h
dhcp-range = 192.168.1.20, 192.168.1.200, 12h

```

## 开启内核转发包服务

sudo nano /etc/sysctl.conf

``` bash
net ipv4.ip_forward = 1     #去掉注释
```
