[21.02.0-rc4]Wan6 does not work properly after adding dns to wwan

Restarting the network service can make wan6 normal, but dns cannot work normally

All software has been updated to the latest

define this ...

that's usually a bad idea ....

Sorry, this is translated by Google. I mean it's useless, it's the same as not filling in dns. Unless I restart openwrt, then the problem is the same as the title.

Which nameservers are you trying to use there?

Use ssh to connect to the device and run these commands:
ping -c 2 google.com; ping -c 2 1.1.1.1

I used 223.5.5.5 and 119.29.29.29 to resolve the domain name that was resolved to 127.0.0.1 by the isp.

/etc/init.d/network restart

Explain that Google services cannot be used in China because of the existence of ‘GFW’

I understand that. However name resolution is working fine with the nameservers you have configured. What other issue are you facing?

Pay attention to the second command, I executed /etc/init.d/network restart

And...
202.102.15*.3 is the dns server provided by isp

root@OpenWrt:~# nslookup fengchen0.**.io 202.102.15*.3
Server:         202.102.15*.3
Address:        202.102.15*.3#53

Name:      fengchen0.**.io
Address 1: 127.0.0.1
Address 2: ::1

I don't see where the problem is.
This name is resolved by both local NS and the 223.5.5.5 and it only has an A record, but no AAAA record.

The DNS server of isp resolved the domain name to 127.0.0.1
So I need to customize dns server

But you have added the custom dns server already, no?

It is invalid after the command /etc/init.d/network restart

I don't follow. What is invalid?

It resolves the domain name to 127.0.0.1 again

Please run the following commands (copy-paste the whole block) and paste the output here, using the "Preformatted text </> " button:
grafik
Remember to redact passwords, MAC addresses and any public IP addresses you may have

ubus call system board; \
uci export network; \
uci export dhcp; \
ls -l  /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/* ; head -n -0 /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/* ; \

Make sure the custom dns are applied. Do a network restart and re-run the commands.

fengchen.zicp.io doesn't by any chance point back to your own openwrt device, does it ?

after booting:
