WIFI 和组播问题
大家好 我有两台 PC 的 A 和 B,它们连接到 LAN1 。A 正在侦听 UPNP 多播地址 239.255.255.250 。 我有一个移动设备 D ,它连接到 WIFI ,并且 WIFI 连接到 LAN1 。 PC A 的 IP 地址为 xxx.yyy.209.80,PC B 的 IP 地址为 xxx.yyy.209.81,设备 D 的 IP 地址为 xxx.yyy.209.82。 如果我从 PC B 向 239.255.255.250 发送多播数据包,它会到达 PC A。 但是,如果我从设备 D 发送多播数据包,它永远不会到达 PC A。任何人都可以告诉我为什么吗?如何解决它?
提前致谢 科兹洛夫
Hi All
I ve two PC's A and B which are connected to LAN1 .A is listening on UPNP multicast address 239.255.255.250 .
I have a mobile device D which is connected to a WIFI and the WIFI is connected to LAN1 .
Ip address of PC A is xxx.yyy.209.80 PC B is xxx.yyy.209.81 and device D is xxx.yyy.209.82.
If I send a multicast packet to 239.255.255.250 from PC B it reaches PC A.
But if I send a multicast pakcet from device D it never reaches PC A .Can anyone tell me why ?How to resolve it ?
Thanks in advance
Kozlov

我意识到这篇文章已有 3 年历史,但以下信息可能对某人有用。我有一个使用 239.xxx 地址的 iPhone 应用程序,但我在使用某些无线接入点时遇到问题。我找到了一份文件,内容如下:
无论如何,我将地址更改为 238.xxx,但这对 Netgear R6100 AP 没有帮助。我在 Wireshark 中发现的问题是 LAN 数据包不会转发到无线设备。我还没有尝试过其他方向。
I realize this post is 3 years old but the following information may be useful to someone. I have an iPhone App that uses a 239.x.x.x address and I have issues with certain wireless access points. I found a document that says the following:
Anyway I changed my address to 238.x.x.x and that did not help with the Netgear R6100 AP. The issue I have seen with Wireshark is that LAN packets are not forwarded to wireless devices. I have not tried the other direction.
