This particular CCNA tutorial describes the various types of NAT (network address translation) you need to know for the CCNA in addition to also also for your career as a network engineer beyond the CCNA. These are relatively basic concepts you definitely need to know if you want to become an effective network engineer. In This particular CCNA tutorial, we will evaluate 3 methods of doing NAT routing traffic through an internal network to the internet:
- Static NAT – This particular can be the simplest in addition to also also more straightforward type of NAT in addition to also also can be also the most restrictive. A static NAT defines a one to one mapping between an internal in addition to also also external IP address. The advantages of using a static NAT can be that will the idea can be very easy to set up in addition to also also few things can go wrong when you are configuring a static NAT. The disadvantage can be that will This particular method requires a global IP address for every NAT entry which might not be possible (or may be very expensive) especially if you are routing to the internet.
- Dynamic NAT (without PAT) – This particular defines a mapping between internal addresses in addition to also also a pool of external addresses. This particular can be similar to the static NAT, however, instead of one external address to map to, there are currently several. This particular can be a more flexible configuration, however, This particular might be an expensive solution due to the cost of internet IP addresses.
- Port Address Translation (PAT) – This particular defines a mapping between many internal addresses in addition to also also one external IP address. In This particular case, many internal addresses can share 1 external IP address in addition to also also This particular can be a cost effective means doing network address translation. PAT can also be configured that has a pool of external IP addresses for maximum flexibility.
I desire This particular CCNA tutorial has helped increase your knowledge on network address translation.
