OpenWrt

Installation

Upload the software to the /root directory of the router with winscp or other tool, and execute the following command to install it.

after openwrt 24.10

apk add --allow-untrusted smartdns.1.yyyy.MM.dd-REL.xxxx.apk
apk add --allow-untrusted luci-app-smartdns-lite.1.yyyy.MM.dd-REL.all.apk

before openwrt 24.10

opkg install smartdns.1.yyyy.MM.dd-REL.xxxx.ipk
opkg install luci-app-smartdns-lite.1.yyyy.MM.dd-REL.all.ipk

Note: For versions before OpenWrt 19.07, please install luci-app-smartdns.xxxxxxxxx.all-luci-compat-all package.

Configuration

Add upstream DNS server configuration to Upstream Servers. It is recommended to configure multiple DNS servers at home and abroad.
Specify the IP address of a specific domain name in Domain Address, which can be used for ad blocking.

Start Service

There are two ways to use the SmartDNS service, one is directly as the primary DNS service, the other is as the upstream of dnsmasq.
By default, SmartDNS uses the first method. You can choose according to your needs in the following two ways.

Method 1: SmartDNS as primary DNS Server

Enable SmartDNS as primary DNS Server

Log in to the router, click on Services->SmartDNS->port, input port 53, smartdns will run as primary DNS Server.

Check if the service is configured successfully

Query domain name with nslookup -querytype=ptr smartdns 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

When the port of smartdns is 53, it will automatically take over dnsmasq as the primary dns. When configuring other ports, dnsmasq is re-enabled as primary dns.
If an exception occurs during this process, you can use the following command to restore dnsmasq as the primary DNS
```
uci delete dhcp.@dnsmasq[0].port
uci commit dhcp
/etc/init.d/dnsmasq restart
```
