DNS resolution for AWS VPN clients

0

I currently have Route 53 set up in one of our VPCs. It works dandy for ec2 instances inside the VPC.

I am trying to make the resolution of the Route53 entries resolve for my computers that are connected to the VPC via AWS vpn. Those computers are using 8.8.8.8 to resolve hosts and so are not resolving the entries I have in Route53.
Is there a way to allow my computers to resolve the Route53 hosts when they are using the AWS VPN?

Thanks for the help

Hi alansilver

Thank you for reaching out :)

To make the resolution of the Route 53 entries resolve for your computers that are connected to the VPC via AWS vpn, you can integrate DNS resolution between Resolver and DNS resolvers on your network by configuring forwarding rules.

You create Resolver inbound and/or outbound endpoints in your VPC. These endpoints provide a path for inbound or outbound queries:

Inbound endpoint: DNS resolvers on your network can forward DNS queries to Route 53 Resolver via this endpoint. This allows your DNS resolvers to easily resolve domain names for AWS resources such as EC2 instances or records in a Route 53 private hosted zone. For more information:
https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver.html#resolver-overview-forward-network-to-vpc

Outbound endpoint: Resolver conditionally forwards queries to resolvers on your network via this endpoint
To forward selected queries, you create Resolver rules that specify the domain names for the DNS queries that you want to forward (such as example.com), and the IP addresses of the DNS resolvers on your network that you want to forward the queries to. If a query matches multiple rules (example.com, acme.example.com), Resolver chooses the rule with the most specific match (acme.example.com) and forwards the query to the IP addresses that you specified in that rule. For more information:
https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver.html#resolver-overview-forward-vpc-to-network

Like Amazon VPC, Resolver is regional. In each region where you have VPCs, you can choose whether to forward queries from your VPCs to your network (outbound queries), from your network to your VPCs (inbound queries), or both.

The below link is a step-by-step guide on getting started with Route 53 Resolver:

I hope this helps!
