I'm getting nowhere with the following problem: When using my local ISPs DNS server at
192.168.0.1 (for example putting it into
/etc/resolv.conf or using it directly with
dig google.com @192.168.0.1) everything works fine, all names are resolved. But as soon as I use any other DNS server (
18.104.22.168 - e.g.
dig google.com @22.214.171.124) nothing works, I get the following error message from
$ dig google.com @126.96.36.199 ; <<>> DiG 9.10.3-P4-Debian <<>> google.com @188.8.131.52 ;; global options: +cmd ;; connection timed out; no servers could be reached
What I did so far:
ping 184.108.40.206to check if I have net access - everything works.
- Checked if the firewall port
53is open - yes, it is.
tcpdump -i eth0 -n -S port 53-
digsends out the requests, I get no responses.
The strange thing is that when I use
192.168.0.1 as the DNS server it works, but as soon as I use any other DNS server I get no response. Can anyone help?
