Openwrt开发之wifi ap设置

拓扑结构：

Wan口接外网或者上级router，lan口和wlan同属一个局域网；

配置/etc/config/wireless文件

config wifi-device 'radio0'
        option type 'mac80211'
        option path 'platform/10300000.wmac'
        option htmode 'HT20'
        option disabled '0'
        option txpower '0'
        option hwmode '11g'
        option channel '11'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option encryption 'none'
        option ssid 'OpenWrt'

接着修改/etc/config/network文件

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd3d:25cc:a776::/48'

config interface 'wan'
        option ifname 'eth0.1'
        option proto 'static'
        option ipaddr '192.168.2.238'
        option netmask '255.255.255.0'
        option gateway '192.168.2.1'
        option dns '114.114.114.114'

config device 'wan_dev'
        option name 'eth0.1'
        option macaddr '00:0c:43:06:76:2a'

config interface 'wan6'
        option ifname 'eth0.1'
        option proto 'dhcpv6'

config interface 'lan'
        option type 'bridge'
        option ifname 'eth0.2'
        option proto 'static'
        option ipaddr '192.168.10.1'
        option netmask '255.255.255.0'
        option dns '114.114.114.114'

config device 'lan_dev'
        option name 'eth0.2'
        option macaddr '00:0c:43:06:76:29'

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option ports '0 6t'

config switch_vlan
        option device 'switch0'
        option vlan '2'
        option ports '1 2 3 4 6t'

然后重启network

/etc/init.d/network restart

测试发现如果开机关闭防火墙，则wifi不可访问外网，需要打开防火墙，在rc.local内加入开机启动防火墙

/etc/init.d/firewall start &
exit 0

如果打开防火墙后外网还是无法访问，可以修改防火墙规则 /etc/config/firewall

config zone
        option name             lan
        list   network          'lan'
        option input            ACCEPT
        option output           ACCEPT
        option forward          ACCEPT

config zone
        option name             wan
        list   network          'wan'
        list   network          'wan6'
        option input            REJECT
        option output           ACCEPT
        option forward          REJECT
        option masq             1
        option mtu_fix          1

config forwarding
        option src              lan
        option dest             wan

增加以上红色部分，使lan口数据可以转发到WAN口，不过这项在openwrt应该是默认配置好的，所以正常情况防火墙规则是不需要另外配置的；
