接入点Iptable /路由规则允许设备发现？ 设备可以手动连接，但不能自动连接。 多播/ Upnp的问题？

我在我的服务器上安装了一个无线接入点，出于某种原因，一切正常，但自动发现function。 我看不到任何其他设备，upnp devives没有被发现，我认为这是一个简单的iptable或路由问题，我失踪了。

例：

• 设备插入的以太网发现20个本地设备
• 设备一个插入无线发现自己和WiFi只
• 设备如果手动指定IP，则插入无线CAN将连接到其他设备
• 设备A可以看到其他的UpNp / DLNA / Share / Etc无线连接，但是可以连接以太网

我很久以前解决了这个问题，但不记得我做了什么。

sudo iptables --list Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT all -- anywhere anywhere Chain OUTPUT (policy ACCEPT) target prot opt source destination
