    Quote Postby ally_uk » 2012/08/30 14:10:34 Hi guys I am having some trouble with getting DNS to work. You list all kinds of configurations but not the one that matters. Likewise, if you see host1_private_IP, replace it with the private IP address of your own server. failed: Temporary failure in name resolution.

Note that the first column consists of the last two octets of your servers' private IP addresses in reversed order.

[[emailprotected] ~]# ping google.com PING google.com (1.1.1.1) 56(84)

    Configure DNS Clients Before all of your servers in the "trusted" ACL can query your DNS servers, you must configure each of them to use ns1 and ns2 as nameservers.
