EntWare

Prepare

When using this software, you need to confirm whether the router supports USB disk and prepare a USB disk.

Install SmartDNS

Upload the software to /tmp directory of the router using winscp, and run the following command to install.

ipkg install smartdns.xxxxxxx.mipsbig.ipk

Modify the smartdns configuration

Vi /opt/etc/smartdns/smartdns.conf

smartdns.conf example:

# set listen port
bind []:53 
# set upstream servers
server 1.1.1.1
server-tls 8.8.8.8
# set domain rules
address /example.com/1.2.3.4
domain-rules /example.com/ -address 1.2.3.4

Note: if you need to support IPV6, you can set the work-mode to 2, this will disable the DNS service of dnsmasq, and smartdns run as the primary DNS server. Change SMARTDNS_WORKMODE in the file /opt/etc/smartdns/smartdns-opt.conf to 2.

SMARTDNS_WORKMODE="2"

Restart the router to take effect

After the router is started, use nslookup -querytype=ptr smartdns to query the domain name. See if the name item in the command result is displayed as smartdns or hostname, such as smartdns

Pi@raspberrypi:~/code/smartdns_build $ nslookup -querytype=ptr smartdns
Server: 192.168.1.1
Address: 192.168.1.1#53

Non-authoritative answer:
smartdns        name = smartdns.

Note: If the service does not start automatically, you need to set optware/entware to start automatically. For details, see the optware/entware documentation.
