Ubuntu 中 eth1 和 wlan0 之间的连接

我有 3 个 NIC，分别是 eth0、eth1 和 wlan0。eth0 通过路由器连接到互联网。DHCP 服务器正在为本地网络的 eth1 和 wlan0 运行。eth1 和 wlan0 上的客户端可以访问互联网。我想要做的是 eth1 和 wlan0 上的客户端在本地网络中相互通信。但是他们没有。这是我的配置。

#loopback
auto lo
iface lo inet loopback

# WAN interface
auto eth0
iface eth0 inet dhcp

# LAN interface
auto eth1
iface eth1 inet static
  address 192.168.100.1
  network 192.168.100.0
  netmask 255.255.255.0

  broadcast 192.168.100.255

# Wireless interface
auto wlan0
iface wlan0 inet static
  address 192.168.200.1
  network 192.168.200.0
  netmask 255.255.255.0
  broadcast 192.168.200.255

请帮助我如何建立 eth1 和 wlan0 之间的连接。

是否配置

我尝试添加如下规则。

iptables -A FORWARD -i wlan0 -o eth1 -j ACCEPT
iptables -A FORWARD -i eth1 -o wlan0 -j ACCEPT

答案1

原因是Windows客户端的防火墙。我没有想到防火墙竟然连ping都屏蔽了。
