We are a small company that is planning to move all of our servers to a datacenter. We will have 5 routable Public IP's. We currently have the same at our office. Our current setup has a Comcast Business Gateway appliance with 3 FW's connected to it. Each of the FW's WAN port is set to one of our Public IP's. We aren't using the other two at this time. I do not believe any of our current FW's can support multiple public IP's coming into the WAN port, but I could definitely be wrong. We have two SonicWalls and a Watchguard. We are investigating purchasing a higher end FW that could support all five of our Static IP's. I'm told we are going to have one Ethernet drop into our cabinet at the datacenter. I"m hoping for guidance on what a typical network design would be to best utilize/manage our five IP's. Multiple FW's? A higher end FW that you can configure multiple WAN ports for each static IP? A FW that has one WAN port that will forward certain static IP's to certain LAN ports with private IP range?

Software/Hardware used:
SonicWall TZ210, SonicWal 240
