Anyone know how to get chromecast talking between the lan, 5ghz, and 2.4ghz
networks on the the same vlan?

I'm trying to figure it out but I'm not having much luck. I think it has to
do with multicast being forward between the subnets, but I'm not sure how
to set up pimd. And I could be completely wrong. ^-^

I've got pretty much everything stock - cerowrt Modena 3.7.5-2 on Netgear
WNDR3800. Any help would be great. Thanks.

Ah, let me explain the problem better.

The chromecast connects just fine via 2.4 ghz. It's unable to connect via
5ghz or ethernet. But to stream to the chromecast you have to be connected
to the router via 2.4ghz as well. If you're connected via ethernet or 5ghz
you can't see the chromecast to stream to it.

I've tried several devices (ipad, android phone, desktop) and they all come
back with the same result. If you connect to the network via 2.4ghz the
chromecast works fine. If you connect any other way, you can't talk to the
chromecast.

I've verified that the networks I'm connecting to are all on the same vlan.

On Cerowrt the 2.4 and 5 Ghz are separate IP networks (not bridged).
Chromecast uses some form of network local communication (Multicast?)
that is not forwarded. For normal users this is a security feature.

In my all too brief test of chromecast

I had to set it up on the same 2.4ghz interface.

After it was setup I could get to it via 5 or 2 or wired interfaces.

I have the chromecast fully set up. But I'm still unable to stream from
other interfaces. What build were you on at the time? Perhaps I need to
update to a newer build.

I set it up again and found four things

1) I CAN reach google play (music) from any interface on the cero box.
2) I cannot reach youtube from any but the interface it is on
3) I cannot reach either service from any other hop on my network.
4) youtube HD pounds my already overburdened 2.4ghz network flat

It appears Chromecast uses UPnP to do discovery.
