I have a customer that has a Cisco 831. They have 2 IP Addresses in the same 255.255.255.0 subnet, but they are not close to each other. Once ends in .227 and one ends in .247. The Internet and the router work fine on the .227 address, however we want to have the Exchagne server use the .247. I have setup a static NAT in the router just liek I have on a dozen or more routers in the past, but it does not work. Normally when I do this I have a full subnet, not random IP's in the same subnet. Does this make a difference?
