无法在 openwrt 路由器上的 LAN 端口之间进行通信

Question

我有一台 WBMR-HP-G300H Buffalo Airstation 路由器，我在上面安装了lates OpenWRT 软件。

除了一个小问题外，一切都运行良好（ADSL、WIFI 等）。我无法在 LAN 端口之间通信。即，如果我在 lan 端口 1 上连接了一台计算机，并且我尝试在 lan 端口 2 上 ping 另一台计算机，那么我会得到“目标无法访问”。

我可以从路由器本身 ping 两台计算机，也可以从无线连接的单独笔记本电脑上 ping 每台计算机。所有计算机都在同一子网范围内 (10.0.0.?/24)。

我怀疑我可能需要在交换机上配置一个 vlan，但是每次我尝试使用各种谷歌配置来执行此操作时，我都会冻结所有 lan 端口，并且必须使用无线连接的笔记本电脑恢复。

这是我的 /etc/config/network：

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

config interface 'lan'
        option type 'bridge'
        option proto 'static'
        option netmask '255.255.255.0'
        option ipaddr '10.0.0.1'
        option _orig_ifname 'eth0 wlan0'
        option _orig_bridge 'true'
        option ifname 'eth0'

config adsl-device 'adsl'
        option fwannex 'a'
        option annex 'a2p'

config interface 'wan'
        option _orig_ifname 'nas0'
        option _orig_bridge 'false'
        option proto 'pppoa'
        option encaps 'vc'
        option atmdev '0'
        option vci '38'
        option vpi '0'
        option username '?????????????'
        option password '??????????????'

任何帮助都会受到热烈欢迎。

这里还有一些配置的东西。

Answer 1

这是从关于您的路由器的OpenWRT 页面复制的：

有线站不能互相ping通

这是一个已知错误：“switch eth0(Atheros AR8316) no traffic between ports possible”根据错误的评论，您可以尝试以下命令：

swconfig dev eth0 vlan 1 set ports "0 1 2 3 4 5"
swconfig dev eth0 set apply

如果这些有效，您可以将以下行添加到您的 /etc/config/network：

config switch
  option name 'eth0'
  option reset    '1'


config switch_vlan
  option vlan '1'
  option device   'eth0'
  option ports    '0 1 2 3 4 5'
