Domain A IP range is 10.0.0.0 subnet 255.255.255.0 gateway 10.0.0.1
Domain B IP range 172.16.1.0 subnet 255.255.0.0 gateway 172.16.1.254
The reason I am doing this is because I am setting up new servers for the company in a remote building. Currently there is no network in the remote building, I have a wireless access point in the main building. The gateway machine connects to the W.A.P., which allows the remote office access to the internet and the old network.
So, from the remote building, I can access anything. From the main building I cannot access anything in the remote building. The pinging will respond from the IP of the W.A.P. but not the IP of the gateway card (pinging from main building).
My eventual goal is to set up a trust between the two domains, once two way communication is established.
This will only be a temporary fix as we are getting a fibre cable between the two buildings but I have no timescale on this and would like to get on with configuring as much as possible.
