0. 禁用系统自带的dns服务

systemctl stop systemd-resolved

systemctl disable systemd-resolved

1. 安装hostapd和dnsmasq

sudo apt install hostapd

sudo apt install dnsmasq

sudo apt install iptables

2. 配置/etc/hostapd.conf

interface=p2p0 driver=nl80211 ssid=RK3288-AP hw_mode=g channel=6 ignore_broadcast_ssid=0 wpa=2 wpa_passphrase=12345678 wpa_key_mgmt=WPA-PSK rsn_pairwise=CCMP wpa_pairwise=TKIP macaddr_acl=0 auth_algs=1

3. 配置/etc/dnsmasq.conf（规避 53 端口占用、仅监听热点）

interface=p2p0 bind-interfaces listen-address=192.168.4.1 dhcp-range=192.168.4.5,192.168.4.50,255.255.255.0,12h dhcp-option=3,192.168.4.1 dhcp-option=6,114.114.114.114 no-resolv server=114.114.114.114 domain-needed bogus-priv

4.使用wlan0连接wifi

sudo nmcli dev wifi connect "你的WiFi名称" password "你的WiFi密码" ifname wlan0

5.使用iptables需要切换

sudo update-alternatives --set iptables /usr/sbin/iptables-legacy

6.启动AP

ip link set p2p0 up

ip addr add 192.168.4.1/24 dev p2p0

killall hostapd dnsmasq

hostapd /etc/hostapd.conf &

dnsmasq &

7.清空旧防火墙规则

echo 1 > /proc/sys/net/ipv4/ip_forward

# 清空旧防火墙规则

iptables -F

iptables -t nat -F

# 关键NAT转发：wlan0是你板子连外网的网卡

iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

8.断开网线，使用设备连接热点
