With a firewall appliance, must Domain controllers and file servers have two IP addresses in order to be available from two offices? A domain is shared between two locations. Routers are mapped to resolve server ip addresses. Once a firewall appliance is in place, and private ip addresses are issued for local machines, will servers require two IP addresses -- the public and private ip address so the other office will still have access?
We want to use 172.x.x.x for internal servers and workstations but resources on servers are shared between offices using 156.x.x.x
