There is a local DNS server on the firewall, but that's where the whitelisted IP address gets generated and the result of the nslookup is the same whether performed on the box or on any other machine in the house since they all use the same box. No, there is nothing in /etc/hosts Apt-get is getting different results from using "host" or "nslookup".
