Site-to-site BOVPNs with same Domain name but unique
I've got a number of sites, each having it's own WIN2016 LAN with same subnets. Each LAN's Domain Name is the same, for ex. "DARK", but they're each unique, too. We'd like to create a site-to-site BOVPN topology that will allow NOC users to access systems remotely at any of the sites. I understand using 1-1 NAT will resolve the duplicate subnets or simply renumbering each sites subnet is better but how do I get around conflicting with the duplicate Domain Names? Block AD services on each BOVPN leg? Changing the sites Domain Names is not an option at this time. Any suggestions would be welcomed.
