Bad address 'openwrt.org

[schumissimo]

Hello everyone, I come back to you with a problem, my three access points are working correctly, they distribute the wifi well, I manage to connect from the outside but when I do a diagnostic I have a message 'ping error: bad address' openwrt.org', on the other hand I can ping 8.8.8.8. I attach my files to you. Thanking you in advance for your help.

Your DNS is wonky. What does the following show?

# nslookup openwrt.org

Thanks for your help. Here is the answer :

I'm not sure if list is the way to go to specify DNS servers. Looks like neither of your DNS servers is being found by nslookup. That's pretty weird, given you're specifying three of them.

If you call one of the DNS servers, like below e.g., does it work?

nslookup openwrt.org 192.168.0.254

If so, then try using option instead of list:

option dns '192.168.0.254,208.67.222.222,208.67.222.220'

[schumissimo]

I modified the line as you suggested to me but it did not change anything.

[Borromini]

At least the DNS server works. Weird that neither list nor option seems to work. I assume just specifying option dns '192.168.0.254 does work?

[schumissimo]

I have already tried deleting the other two DNS servers but it doesn't work either.

I found the solution to my problem, I had to deactivate dnsmasq.

Glad you solved it. In the future, please consider copy/pasting your output instead of using screenshots, those are not searchable, unlike full text.

Thank you very much I take note of your remarks;)
