I have a VPN setup between multiple locations. Between each location and the central point (me), is a trust between our domain controllers. It all works great..
A new location wants to join, but their AD controller is using an IP address that is already in use by another AD in a separate location.
Neither locations can change their IP addresses, but apparently there is a NAT rule that could be used to allow communication between each AD controller? The central site has a Cisco 5510 firewall which could perform the NAT, but I am unsure of the logic behind the NAT rule.
Is anyone able to explain or help out? Thanks.
