Feature/Application

This article describes how to block YouTube videos using App Rules. This is accomplished by blocking the DNS Queries for googlevideo.com, which will not only block videos directly on YouTube but also linked YouTube videos on sites like Facebook. Similar blocks can be setup for other Domains by following this article and substituting any Domain you wish.

Note

1. This solution blocks DNS Requests and Responses only. If a video is paused before enabling this rule, it will be able to resume play. However, when attempting to play a new video, it will be blocked. Likewise, when switching from an "outside" wireless network, where this rule is not enforced, to a network behind the SonicWall with this rule enabled, new videos will be blocked though paused / ongoing videos will play.

2. The solution described here will impact other applications which depend on the Google Video server to play videos. For example, YouTube videos linked through Facebook.
