General Discussion / Re: UDP Broadcast Relay
« on: March 08, 2022, 01:07:06 pm »
So I think I have a bit of strange problem. I have setup UDPBR as per the guide for mDNS (specifically for Chromecast devices. As most people seem to do, I have my IoT vlan and my main LAN. Currently they're both wide open to each other as I test things. While I was able to see and connect to the various chromecasts, the connections would randomly drop out. This was especially apparent in the home app where you could see devices appear and disappear.
I then installed IGMP Proxy and configured the upstream as my LAN and my downstream as my IoT vlan. If I have both services running, Chromecast connections are rock solid (and extremely fast to discover). The weird thing though, is in my logs, I have warnings from IGMP proxy that various multicast addresses are in use, which I assume is due to UDPBR using them.
EDIT - Just tested mDNS Repeater and it works as expected without IGMP Proxy enabled.
EDIT 2 - Spoke to soon. Without IGMP proxy installed, some devices don't load in the Google Home app even with using mDNS.
Any thoughts on this, or anyone else see this?
Thanks in advance!
