fe80 adress is what the client gives itself like a 169.254.x.x for ipv4.

The router can also have an fe80 address if the ipv6 module is loaded.
This can be the case if you use e.g. wireguard which does not run without ipv6 module. This will happen even if you have ipv6 disabled

Hello.

I need help. I need current instructions, since the guide in this forum is from 4 years ago, It's not accurate from what I've seen. Or I could be wrong.

So I had SmartDNS running for months until it all of a sudden stopped while I was out of town. I run DNSMASQ for my local DNS. I have a jffs usb drive mounted, where my dnsmasq and hosts entries are located.

Code:
I am running Firmware: DD-WRT v3.0-r54604 std (12/26/23). My ISP is Xfinity. I have no issues using regular DNS which is overridden to 8.8.8.8, 8.8.4.4 and 1.1.1.1.

Code:

My DHCP network is 192.168.10.0 and my router is obviously 192.168.10.1.


I have a number of secondary wifi routers in order to increase bandwidth for different devices (connnected house by only through manual operations - no magic). I also have a number of bridges and routes and port-forwarding settings but these should not in theory conflict. All VPNs on DDWRT are disabled.

I would like to use only the hosts below plus my DNSMASQ. I had to reset my DHCP and turn off my SmartDNS to get back on the internet and now I want to set up smartDNS correctly.

Please help me with the most current settings to use. Feel free to ask any additional questions. I will post any additional details. I have no way to debug SMARTDNS since I am running the default version that came with my DD-WRT but I'm willing to experiment if required and if the first attempt to setup SmartDNS fails. My thanks in advance.

Here are the servers/settings that I did manage to save. TBH, I collected them from one of these forums. As you can see, I only picked the privacy enhance no logging servers. Or at least that was the intent.

Please help me configure:
Code:
DNSMASQ
SmartDNS

So that they can run peacefully together like they were before.

Code:
server-tls 1.1.1.1:853 -host-name cloudflare-dns.com -tls-host-verify cloudflare-dns.com
server-tls 1.0.0.1:853 -host-name cloudflare-dns.com -tls-host-verify cloudflare-dns.com
server-tls 9.9.9.9:853 -host-name dns.quad9.net -tls-host-verify dns.quad9.net
server-https https://1.1.1.1/dns-query -host-name cloudflare-dns.com -tls-host-verify cloudflare-dns.com
server-https https://1.0.0.1/dns-query -host-name cloudflare-dns.com -tls-host-verify cloudflare-dns.com
server-https https://9.9.9.9/dns-query -host-name dns.quad9.net -tls-host-verify dns.quad9.net
server-tls 8.8.8.8:853 -host-name: dns.google.com -tls-host-verify dns.google/dns-query
server-tls 8.8.4.4:853 -host-name: dns.google.com -tls-host-verify dns.google/dns-query
server-https https://8.8.8.8/dns-query -host-name dns.google.com -tls-host-verify dns.google/dns-query
server-https https://8.8.4.4/dns-query -host-name dns.google.com -tls-host-verify dns.google/dns-query
