Have a lab project using a Watchguard firebox splitting two interfaces internally trusted/trusted. One interface is 192.168.1.0/24 the other is 192.168.7.0/24. An existing 2008 R2 forest/domain is parked on the 1.x subnet. I want to create a 2012 forest/domain on the 7.x side. Any problems with these co-existing? Not planning to establish trusts, everything is static, no DHCP.
