For this lab you need to set up two things:
1) Set up a static nat exchange using your internal server as the inside address and on the outside using the 10.0.x.100 address (where x is your designator).
2) Set up a PAT pool of addresses to allow other systems inside your network to access the outside world using the 10.0.x.200 address.
Test both configurations (you may need to set up a virtual interface on your server to do this) (or you can connect your laptop to your switch).
ipconfig int eth0:1
If you don't know how to do a virtual interface in linux, google it.
Provide screen shots of pings through your system. A copy of the conf should be attached to this lab. (copy and paste).
