To make the development environment identical to the production environment, configure your client to override the authoritative DNS server(s) for the commonidtrust.org domain to the development environment.
Currently, the DNS server for VPC-Dev runs on a personal, free t2.micro instance in EC2 and is accessible at 184.108.40.206. You will need a secondary resolver for real addresses, such as 220.127.116.11, 18.104.22.168 (Level3), or 22.214.171.124, or 126.96.36.199(Google).
DNS Client Configuration:
VPN with L2TP over IPSec
Alternatively, you can just VPN to the machine and the DNS settings will default to 188.8.131.52 and 184.108.40.206.
On a Mac, go to Network. Click the +. Select VPN as Interface. Name the service whatever you want.
Server Address: 220.127.116.11
Email firstname.lastname@example.org to ask for the password and shared secret.
yum -y install bind
Configure /etc/named.conf and the zone file /var/named/masters/commonidtrust.org (see examples attached).
chkconfig named on
named logs to /var/log/messages
This is configured to serve up the A and/or CNAME records for account.commonidtrust.org, helpdesk.commonidtrust.org, and login.commonidtrust.org for the specific VPC environment.
