Network Address Translation is a great protocol, but you need to understand when you should use Static Network Address Translation, Dynamic Network Address Translation, or NAT overload, also called Port Address Translation. This video will show you how Static NAT is used and when, and provide information on how you might use static NAT along with NAT overload on an enterprise network.
- [Instructor] So there's three different types of NAT.…Static NAT, dynamic NAT,…and PAT, or Port Address Translation,…which is the most popular today…and the reason that we have not run out of IPV4 addresses.…So with static NAT, we have a one-to-one address mapping.…Pretty impossible just to use this today.…Absolutely impossible, not pretty impossible,…absolutely impossible.…For dynamic NAT, we have many-to-many,…it's still really a one-to-one,…but it allows us to create a pool.…And this pool can have many addresses…that users can use to get out onto the internet…and then put it back in the pool when you're done.…
Again, not usable for today's networks.…Port address translation is a many-to-one address mapping.…So theoretically,…I can use up to 65,000 internal hosts…using one global address…to get out onto the internet.…Let's go ahead and take a look…at the commands to configure static NAT,…then we'll go ahead and run out and do it.…First off, we're gonna go ahead and put our IP addresses…that we use underneath our interfaces.…
