How to allow chromecast to work through SonicWall when Device and Chromecast are on separate Zone

03/26/2020 78 12217

DESCRIPTION:

SonicWall does not allow chromecast to work through it by default

CAUSE:

Chromecast require enabling multicast traffic through the SonicWall. As it is not enabled by default on SonicWall, that is why chromecast does not work through SonicWall.

RESOLUTION:

Please see the following Solution to enable multicast on SonicWall

Enabling Multicast[[|170505657227589]]

We need to enable multicast on the firewall as well as the interfaces associated with chromecast

**This solution is for the case if the client and the Chromecast are on separate Zones**

We need to be sure of the following :

1. Your Client (Device trying to Connect to Chromecast) and your Chromecast are on SEPARATE zones. For example: Client is on the LAN and the Chromecast is on say, a wireless zone.
2. The Wireless Access Point(s) that the Chromecast is connected to are already configured for Multicast 

Now to get chromecast to work with SonicWall, Please do the following:

-Under Firewall setting> Multicast, Uncheck the box titled Require IGMP Membership reports for multicast data forwarding

-Select the radio button titled: Enable reception of all multicast addresses

-Click Accept at the top

- In the Firewall > access rules, Make sure you have allowed the traffic from the zones associated with Chromecast and the multicast zone.

E.G. LAN > MULTICAST > Allow> any> any

Note: Multicast zone is automatically created when we enable multicast on SonicWall under Firewall settings
