I have some servers at a co-lo facility and I want to change from a SonicWall to a PIX 506. I have a range from my co-lo of 64.X.X.225 to 64.X.X.238. I currently have the SonicWall at 64.X.X.225 and my servers all have public IP addresses.
Since the SonicWall and PIX do things different, I have to use 2 IP addresses on the PIX. I want to set up the PIXs INSIDE interface to be 64.X.X.225 (to keep the gateway on the servers the same) and then make the outside IP address be one of my unused IP addresses.
Is that doable? Or is there a better way to handle it? Will I need to subnet this out a little in order to make it work?
