I've a very complex network to manage.. I don't know where to start from ? Here's a Diagram:
Now... I want to give Internet Access to #1, #2 and #3 ..simultaneously giving access to Billing and Scanning Networks & all the other clients under it.
-- We cannot combine Billing and Scanning.
-- Later PC's 1,2 & 3 would also be restricted to some websites.
-- MiddleWare is also being used as a workstation.
-- There's a switch that connects the 3 PC's to middleware.
Everything is working fine right now. But when I want to connect to the internet, I've to disable the NIC that connects to scanning & Billing, and When I activate these two the internet goes down.
PS: When I say internet is working or Internet goes down... it's on the Middleware that I'm working on (We are using it as a workstation also).
