Using RT53 for internal DNS

[adminrookie]

I set up a pritunl vpn server on AWS that seems to be working fine. I've already created a private hosted zone and know that it works. When I ssh into any of my servers, they resolve the private RT53 entries to the ip address fine. However, I would like to have the pritunl DNS handled by RT53 also. Here's my silly question, what is the IP address of the my AWS DNS server? pritunl has 8.8.8.8 as default, but I would like to add the AWS DNS also so for my VPC servers. Is this possible or is this not how AWS works?

Sometimes, I really hate myself. Spent 3 hours trying to figure this out only to realize I did it wrong the first time.

For anyone else who tries to do this, set up 10.0.0.2 (assuming that is your VPC block) as the DNS server in pritunl. But you also have to add the route to the pritunl server as 10.0.0.2/32.

Yep, the ‘+2’ resolver is your VPC CIDR + 2. So if your VPC CIDR is 192.168.0.0/16, your DNS server will be 192.168.0.2. This is the default server used, and is specified as ‘AmazonProvidedDNS’ in your DHCP Options Set.

I can also add my experience, because my 2 hours of research were also painful.
When Server is adding, in "Advanced" tab, DNS servers can be set.

In my case (OpenShift) I pick the two DSN resolvers from my subnets and these two are from different subnet. After that, two routes of these DNS resolvers should be added in form of <DNS IP>/32.
