Best set up for NAT

Question

You have received and e-mail from a user in your company. He has set up a network at his house and everything, at least in his mind, has been working well. He is now moving to another house and wants to move his servers. His question is this:

"When I move to a new location soon, they will only give me five IP addresses for the short term. I was wondering what would be the best set up for NAT on these servers. I will have a total of seven servers at my house. The IP addresses need to be split as two for DNS servers and then the other three I want to use for clients needing SSL."

"How do I set this up?"

Answer 1

Buy a router and set up NAT on that. All the computers and servers on your network should be on a private 198.xx.xx.xx network. You can assign them static addresses or have the router assign them dynamically. Use one of your static public addresses for the "outside" port on your router. Everything else will be assigned private addresses so that nothing on your network is exposed directly to the Internet.
