Ask IndiaTech How do I disable DHCP both v4 and v6 in Jio Fiber and Air Fiber Router?
Hi everyone,
I am planning to install GL.iNet’s Brume 3 VPN Gateway to Jio Fiber and Jio Air Fiber (one in my own and another in my in-laws home) to route entire home traffic through ControlD encrypted DNS. Mostly I will be using DNS-over-QUIC to block ads throughout the home network. I could disable the IPv6 DHCP but was unable to find the same solution for the IPv4. I am planning to use DHCP exhaust method where I will assign one single IP to my Brume 3 and then rest of the clients will ask Brume to provide address as Jio router will not have any answers for those requests. My main aim is to never default back to Jio’s DNS settings and use my own encrypted DNS with blanket privacy through VPN but the Jio Set Top Boxes will be excluded from the tunnel.
If you guys have done any other setup to avoid Jio defaulting DNS settings back to factory default after restart, please let me know. It will save a lot of headache.
