Chromecast Firewall Settings

Hello all,

 

I'm trying to figure out how to get a Chromecast device working over our Aruba wireless network. I'm assuming that it's not working because a port, or ports, need to be opened on the firewall.

 

Does anyone have any experience with this?

Chromecast service discovery requires both the Chromecast and the client device to be on the same layer 2 segment (similar to Apple devices). It uses the DIAL protocol.

Re: Chromecast Firewall Settings

the chromecast and the laptop are both on the same segment. What else needs to be done? I know there a certain UDP port has to be opened but I'm not sure which and how to do it.

The service discovery uses multicast. Do you have drop broadcast/multicast enabled? 

 

This is the same situation as AirPrint and AirPlay. AirGroup captures the multicast discovery and service requests.

Re: Chromecast Firewall Settings

yes, Drop Broadcast and Multicast is enabled becasue i think Airgroup requires it. Where do I go from here?

Chromecast will not work with drop broadcast/multicast enabled.

Depending on what you have for APs installed, you can upgrade next year to our next version.  We are looking at adding support for Chromecast to the AirGroup feature.

Re: Chromecast Firewall Settings

We are currently using AP-105 in classrooms and AP-93H in our dorms.

 

When is the next OS release going to include support for Chromecast in Airgroup?

Re: Chromecast Firewall Settings

Please work with your account team for more specifics. You can expect something in the first quarter of next year.

Re: Chromecast Firewall Settings

Both of those APs will be supported.

 

This OS will most likely drop in early 2014.
