If you want to block devices to access certain websites through the router, you can set up a Domain Filter to achieve it.
Step 1: Open a web browser and go to http://cudy.net or http://192.168.10.1.
For details, please refer to How to log into the web interface of Cudy Router?
Step 2: Click Advanced Settings -> Domain Filter in the Security section.

Step 3: Check the settings on the Domain Filter page.

• To block the specific IP address(es)
1. Select 'Allow all except list'.
2. Type in the domain name(s) you want to block.
Example: All devices are not able to visit YouTube.

3. Save & Apply the operation.
• To allow the specific device(s)
1. Select 'Allow list only'.
2. Type in the domain name(s) you are allowed to access.
Example: Only allowed to visit YouTube, the other website will not be able to load.

3. Save & Apply the operation.
Note:
1. If you also want to limit other websites, please click 'Add' to add new entries. One entry can only type in one website.
2. When you don't want to limit the internet, choose 'Disable' from the drop-down list and save the settings, not only 'Delete' the item.

@Dear Oliveira,
Thank you for your kindly advice. We have plan to add the adguard function.
Regarding the WOL funciton, we also have plan to add it to the Cudy APP.
I think it will be not a long time. Please wait patiently.
“Plus 1 to Luis comment. Please allow the use of a list by importing a txt file, or by inserting a link to a txt file that automatically gets updated once a day, something similar to AdGuard, or just add AdGuard to the router if possible.
Maybe allow to install some applications as well, like eth-wake to mage to send Wake-on-LAN signals to devices in the network (I use WoL all the time in my router, but I need a router with 5G connection, and considering buying yours)."

Dear Luis,
Thank you for your kindly advice, We will provide your feedback to the product department for evaluation.
“Could yo add the feature to set lists like its done with adguard home or pihole? blocking domains one by one is not really useful.
Being able to set those lists and the router retrieves periodically and block the domains there would be awesome. I know I can do it flashing OpenWrt, but your mobile app is so convenient that I’d prefer not flashing it.
Thanks!"

Dear Customer,
Thanks for contacting the Cudy support team.
You can set “youtube.com” or “youtube”, and have a try. If it doesn’t work well. You can try use a chrome to open the youtube.com and click the F12 to check all the domains that the website use and add it to the domain list. As shown below. This is an example of the www.qq.com. Open it via chrome, and click F12 to check all the domains.
