What's the simplest way to block a Top-Level-Domain (*.ru/* for example )in web protection?

I know this works in UTM hoping XG

https?://[A-Za-z0-9.-]*\.ru/

or

http?://[A-Za-z0-9.-]*\.ru/

You can also use country blocking, you may be aware but figure I would mention it.

Hello

You can use those regex for allowing on XG at Web > Exceptions but for blocking a top level domain you can use firewall rules

Action Drop

From Lan to Wan

From Any to FQDN Host - *.ru

Log if you want.

There are some other options like creating url groups, or web categories -Need to write all domains and subdomains in this- but i always prefer Firewall Rule for this.

Trying to add a FQDN Host for "*.ru" (no quotes) but it won't allow it, showing this:

You must enter a valid value for FQDN
