Here is my situation, I have a main network at our main office with a Sonicwall TZ200 router that connects to 8 remote locations via VPN that have sonicwall tz100 routers. Each remote location has its own subnet and the router at the location is handing out the IP addresses. We want to keep them on their own sub nets and still bring them into the domain. So far I haven't done anything to get this started as I want to know what I am doing before I get started and possibly screw something up. I am fairly sure that it is doable and would not be all that hard but if I just start going for it and don't know what I am doing first it could cause me some real headaches. I know that it will require some routing policies and probably some other policies to get everything to talk correctly. Where should I start?
