We have a firewall for the outside then another firewall internally that will sit between Exchange 2010 on Server 2008 R2 and our internal network. There is a Server 2008 R2 domain controller on the internal network. how can I setup AD to replicate between the two servers. They have separate subnets of 192.168.2.x and 192.168.1.x
We can not setup VPN between.
