Chromecast - Fortigate - Multicast

[reuben_chin]

I have a FW80CM and a Chromecast.

The issues I have are possibly because of multicast.

I have read the following KB article:   http://kb.fortinet.com/kb/documentLink.do?externalID=FD39305

But the KB article is about a Chromecast not on the same VLAN as the users.

My issue is simple.

The Chromecast is on the same subnet as my IOS devices or laptop.  (Same VLAN)

SSID Intra-Blocking is disabled.

I can ping between my laptop and the Chromecast just fine.

However, using the Chromecast app on the iPhone or laptop I still cannot see the Chromecast device.

When I use the laptop to setup the Chromecast manually, I can see that its connected to the SSID.  But any attempt to connect to it is failed.

Any help with this would be greatly appreciated.

Thanks,

Reuben
