I have a project group that wants to set up some temporary compute instances on AWS. Easy enough. The trick is they want the instances to be connected to our domain so users can authenticate normally and there is no differentiation in their experience when using these systems. I've never joined a machine to the domain through a VPN connection, but I know it's possible
We've set up a VPC with a 10.x.x.x/24 CIDR block, traffic can pass through and I can remote to the instances I've created there. When I attempt to join the domain, it errors out, stating it cannot contact the AD DC. I've checked firewall settings, had ITSEC check out the VPN and can't find the problem. Can anyone help?
