We have a router on the outside with a address of 172.31.*.*/24 and on the inside we have 10.1.2.*/24, the inside needs access to anything on the outside. We as the outside needs access to 1 server on 1 address10.1.2.*/24.
The solution we have is: NAT the 10.1.2.*/24 to an address on the outside of the router 172.31.*.* and NAT the whole of the inside to 1 address on the outside overloaded "BUT" we can't seem to figure out how to NAT/Configure it to work correctly.
