I have been using CBT Certification Training packages from different companies for quite a long time. Since I got my first package of CBT Nuggets, I never looked back to attending certification training classes.

So why do I say that CBT certification training is more useful than the traditional methods of training. The first reason I have is that I can watch the videos and read the learning material unlimited number of times while if we’re in a training class, we get a chance to listen to the teacher only once.

While on a router console we run quite a no. of commands. Some commands execute immediately and other require some time to finish. Some of them are waiting for the user input. For example if we open a telnet session within the router console or router telnet session, then we need some way to come back to our original console prompt.

To break out or exit from a running command like telnet just press CTRL – SHIFT – 6. This command will take you to your original prompt.

Last time I had given the latest version of Pass4Sure dump in July 2009. I didn’t follow what was going on in the dumps race. Now so many people have requested me to update the dumps and other helpful material for certification regularly. I will definitely try to update everything as much as possible but I would need your help to achieve this. If you want to ask for any specific material like lates pass4sure dumps or router simulators etc, kindly ask me in comments. And if you have anything to share, email me and I’ll post it in your name.

I’m planning to have a forum where we can share everything like this. Today I’m going to share with everyone the latest version of Pass4Sure CCNA 640-802 Exam which was updated in January 2010. There are 60 questions in total and it’s in the form of a Word document. It can be downloaded from the following URL:

First we look at what exactly NAT is? It means Network Address Translation. This technology or technique was developed to overcome the shortage of public IP addresses in IPv4 standard. With the invent of NAT, the problem of shortage of public IP addresses has been solved quite a bit. Now we have moved to IPv6 which has a lot more addresses than IPv4 but still most of the world uses IPv4 in combination with NAT.

If anyone wants to dig down deep to understand NAT, he can go to the following Wikipedia article:

http://en.wikipedia.org/wiki/Network_address_translation

Now let’s start by configuring a basic NAT on a Cisco router. The type of NAT we are going to configure here is Overloading. This means that we will map one public IP address to many private or local IP addresses.

This is a fairly easy question but if you’re a newbie in Cisco routers, then this can be a handy guide to tell you the details.

To see the version of IOS, there is one command which give a detailed overview of the software installed on the system (Cisco router or switch).Lets issue the command:

Certhacker#show version

The following sample information will be shown:

As the title suggests, I want to have a limited access to my router through telnet. I want only specific networks to be able to telnet my router. All others should be blocked from telnetting the router.

So let’s start:

Enter global config mode

Certhacker#configure terminal
Enter configuration lines, one per line. End with CNTL/Z
Certhacker(config)#

Create Access list to permit a network
