I am trying to replicate the steps in this post. However, When I get to the step where I create the ad connector, it fails with the following error:
Connectivity issues detected: DNS unavailable (TCP Port 53) for IP 10.0.0.4, DNS unavailable (TCP Port 53) for IP 10.0.0.5. Please ensure that the listed ports are available and retry the operation
I am very proficient with AWS. However, I'm struggling with Azure and feel I may have misconfigured something. I have carried out the following steps thus far:
In Azure, I used an existing resource group and created "Azure AD Domain Services" instance using default configuration
Basics
- Name: sy******k.com
- Subscription: Pay-As-You-Go
- Resource Group:
- Default Region: UK South
- SKU: Standard Forest type: User
Network
- Virtual network: (new) aadds-vnet
- Subnet: (new) aadds-subnet
- Subnet Address: 10.0.0.0/24
- Network Security Group: (new) aadds-nsg
I created a site to site vpn connection with azure virtual network. However, I am not sure about this step in the post: "The tunnels must be configured to allow traffic from your AADDS endpoints and the Subnets" How exactly do I do this?
In AWS VPC cidr is 10.1.0.0/16 and both tunnels between AWS VPC and Azure Virtual Network are up and connected. I tried to contact the post author: "Justin Stokes" directly but can't find any emails for him. I cannot find a single online guide on how to set this up step by step along with the site to site ipsec setup. It would be very very helpful if someone can provide a video tutorial for this step by step from A-Z instead of leaving a chunk of the steps out of the guide.
The troubleshooting guide here suggest that the firewall i.e. network security group is not allowing port 53TCP/UDP inbound for AD Connector. But I updated the networks security group as a test with a rule to allow any source, any destination and any port and still I'm getting the same error.
