Chinadns does not use upstream dns server of internal IP

[bingzhangdai]

First, I have an ISP provided DNS 192.168.1.1

root@OpenWrt:~# dig -p 53 @192.168.1.1 hmajax.itheima.net

; <<>> DiG 9.14.12 <<>> -p 53 @192.168.1.1 hmajax.itheima.net
; (1 server found)

I also have a dns forwarder

root@OpenWrt:~# dig -p 5300 @127.0.0.1 hmajax.itheima.net

If I set up the china dns using 114.114.114.114 and 127.0.0.1:5300, everything works fine

root@OpenWrt:/e/dnsmasq.d# /usr/bin/chinadns -m -b 0.0.0.0 -p 5355 -s 114.114.114.114,127.0.0.1#5300 -c /etc/chinadns_chnroute.txt -v -d
Thu Jan 25 13:26:40 2024 request hmajax.itheima.net from 114.114.114.114:53 127.0.0.1:5300
Thu Jan 25 13:26:40 2024 response hmajax.itheima.net from 114.114.114.114:53 - 223.5.179.239, pass
Thu Jan 25 13:26:40 2024 response hmajax.itheima.net from 127.0.0.1:5300 - 223.5.179.239, filter

If I use 192.168.1.1 and 127.0.0.1:5300, chinadns does not query 192.168.1.1
