Re: Setting up a local DNS server but clients that use it can't access the internet




Firstly thank you all very much for the replies, and sorry for the vague information, that wasn't intentional I didn't know what you would need and also I wasn't aware of the commands you ask for the output from.

Please invoke this on one of the problematic client hosts:

dig in a debian.org +trace +recurse

dig in a google.com +trace +recurse

What is the output of 'ip addr ls' and 'ip route ls' on one of the Linux
clients? What are the contents of /etc/resolv.conf and /etc/hosts on one
of the Linux clients? What are the contents of /etc/bind/named.conf*
(that is, all the configuration files with names starting with
/etc/bind/named.conf)? What is the actual output where you see errors?
For example, if nslookup fails, please provide the complete command-line
and the complete error output. Same for apt-get or any other thing that
is failing.

What domain name did you choose for your local area network?

Domain name: nhs2.uk
 
What software are you using on the DNS server?  How is it configured?

Software: Bind for DNS - Configured as per the instructions here: https://help.ubuntu.com/lts/serverguide/dns-configuration.html
 
Did you use a combined nameserver + recursive resolver on a single
host, or did you separate the functionality?

I am not sure, I think I have only configured a nameserver, I basically just followed the instructions in the ubuntu dns configuration guide.
 
Plus, all the other excellent questions others have already given.
In short, you must give details.  All of the details.

Thank you,
