I am currently trying to get a Google Chromecast device to work through my Ubuntu 13.04 based computer. Currently, the Google Chrome extension shows "no devices found" as long as my UFW firewall is enabled.
If I disable the firewall, I am able to see my Chromecast device without any issues.
I notice that every time I click on the Chromecast browser extension a new port is opened up by the Chrome application. It is a different port every time.
Is there a way to set a rule in UFW that would always allow the chrome application to access any port it wants? Is there a name for this type of behavior?
The port that chrome is using changes every time I try to find the Chromecast device. I imagine I won't be the only person having this issue.
