Hello I'm kind of new to networking and I'm having a small problem of.. not knowing where to start.
I have three Windows2012 servers which I would like to assign three IP's from my range given by Frontier.
My network goes as follow, ATT Rack -> Small Business Cisco Router RV042G -> SonicWall NSA 2400 (Passthrough, L2-Bridge) -> Switches -> Server A (DNS, DHCP, AD DS, DC), Server B (IIS,FTP), Server C (IIS,FTP).
My ideal set up would be to have, x.x.x.178 ServerA (RDP Only) x.x.x.179 ServerB (HTTP,FTP) x.x.x.180 ServerC (HTTP,FTP)
A consultant CCNA told me it was not possible with the current hardware, he said I would need something capable of proper NAT routing. So this is where I am stuck.
At the moment I am only using x.x.x.178. HTTP is port-forwarded to ServerB, while RDP is forwarded to ServerA. This was done through the Cisco Router Web Interface, and the sonicwall is passing through all traffic for now.
I'm completely new to networking and I would appreciate any pointers in the right direction.
