Hello,

 

Do you already have NAT configured on the device? If so, you should just be able to add a static NAT statement like so:

 

ip nat inside source static 10.0.0.2 interface gig0/0

 

Or even better would be to lock it down to a particular port so that all traffic doesn't go to the server:

 

ip nat inside source static tcp 10.0.0.2 80 interface gig0/0 80

 

The above would allow port 80 through but nothing else.

 

Hope that helps!
