我正在尝试使用 hostapd 配置 Linux 机器,以使用 wlan0 接口作为接入点。eth0 是唯一连接到路由器的以太网端口。我能够连接到接入点,并且它可以访问互联网,但是当 hostapd 正在运行并且 wlan0 接口已启动时,我无法在机器本身上访问互联网(无法通过 SSH 进入机器,也无法更新 NTP)。
拓扑 br0 = eth0 + wlan0 && br0 stp = ON && linux ipv4_forward 已启用
网络过滤器 iptables 或 ebtables 规则均未生效(全部接受)
以下是/etc/网络/接口
auto lo br0
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet manual
allow-hotplug wlan0
iface wlan0 inet manual
iface br0 inet dhcp
bridge_ports eth0 wlan0
pre-up ifconfig eth0 0.0.0.0 up
pre-up ifconfig wlan0 0.0.0.0 up
pre-up brctl addbr br0
pre-up brctl addif br0 eth0
post-down ifconfig wlan0 0.0.0.0 down
post-down ifconfig eth0 0.0.0.0 down
post-down brctl delif br0 eth0
post-down brctl delbr br0
以下是输出brctl 显示
bridge name bridge id STP enabled interfaces
br0 8000.00c0ca8ffbc5 yes eth0

以下是 /etc/hostapd/hostapd.conf 的内容

其中192.168.1.1是路由器的IP。
如果我运行以下命令,我就能访问盒子的 SSH 并更新 NTP。
ifconfig wlan0 down
service hostapd stop
我怀疑路由表不正确,或者其中一个条目的度量无效。感谢您的建议!
