Enforce SafeSearch on LAN Clients (DrayOS4)
This video walks through how to enforce SafeSearch for all LAN clients using a DrayTek router. This guide focuses on the manual configuration required in DrayOS 4 to ensure content filtering is applied automatically across your network. SafeSearch is a feature provided by major search engines like Google and Bing that helps filter inappropriate or explicit content from search results. It's commonly used in workplaces and schools to create a safer browsing environment. When SafeSearch is enforced at the network level, it applies to all devices on the LAN and helps prevent users from bypassing the setting by changing their browsers. The LAN DNS feature on a DrayTek router allows network administrators to enforce SafeSearch regardless of individual user settings on their devices.
