Yes, you can connect to a work VPN and use Cloudflare Family DNS as your router's DNS settings.
You're updating your router's DNS settings to Cloudflare's secure network, which helps block malware. You're also worried about potential disruptions for your brother who uses a VPN at home and connects through his personal PC. Make sure the new DNS configuration remains stable so his remote connection isn't affected.
A DNS server can't truly stop a VPN or malware connection. It might just say it won't resolve the hostname, but once the IP address is found, the DNS part is irrelevant. After that, the link between home and office is complete. The idea that their DNS blocks malware is more about selling a service than actual protection. In reality, they usually block only known malicious domains or content. They can't actively prevent the connection. It's similar to claiming your phone book blocks calls to adult lines—it might not list those numbers, but they still exist and can be reached through other means. If someone is curious about DNS, they could switch to a different server or use a local caching solution like a RasPi for better control.
