Host The device performs Steps 2 to 5 for each packet that it receives.

Overloading of Inside Global Addresses You can conserve addresses in the inside global address pool by allowing a device to use one global address for many local addresses. When overloading is configured, the device maintains enough information from higher-level protocols for example, TCP or UDP port numbers. This action translates the global address back to the correct local address. When multiple local addresses map to one global address, the TCP or UDP port numbers of each inside host distinguish between local addresses. The following figure illustrates a NAT operation when an inside global address represents multiple inside local addresses. The TCP port numbers act as differentiators.

Figure 2. NAT Overloading Inside Global Addresses The device performs the following process in the overloading of inside global addresses, as shown in the preceding figure. Both Host B and Host C believe that they are communicating with a single host at address how to configure web server in cisco packet tracer Whereas, they are actually communicating with different hosts; the port number is the differentiator. In fact, many inside hosts can share the inside global IP address by using many port numbers. The user at host Based on your NAT configuration the following scenarios are possible: If no translation entry exists, the device determines that IP address If overloading is enabled and another translation is active, the device reuses the global address from that translation and saves enough information. This saved information can be used to translate the global address back, as an entry in the NAT table.

This type of translation entry is called an extended entry. The device replaces inside local source address When the device receives the packet with the inside global IP address, it performs a NAT table lookup by using a protocol, the inside global address and port, and the outside address and port as keys. It translates the address to the inside local address The device performs Steps 2 to 5 for each packet it receives. Overlapping networks result when you assign an IP address to a device on your network. This device is already legally owned and assigned to a different device on the Internet or outside the network.

The following figure shows how NAT translates overlapping networks.

Figure 3. Once the router is configured correctly, the red dots will turn green to indicate the devices are able to communicate. Click on your router to bring up the configuration menu and verify that it is turned on. When on, there will be a small green light below the switch as seen in the diagram. Next we have to open the Ethernet ports to allow communication. Although they are physically connected, they are in a state that is known as being in administrative shut down.

Now click on the CLI tab to access the configuration menu. Type enable to get to privileged mode this gives you more options in configuring the router 3. Type config terminal or config t for short to access the configuration menu. Type ip address Type no shutdown to open the interface up for business. Wait a bit. A new screen appears confirming settings are successful. You can click on continue to continue with configurations. To test for the new password entered, close the browser of Admin PC and try to to access the GUI again using the browser.

The admin username and password are important, as only a network admin or a user with admin rights is able to log into the router and manage its settings.

The default LAN network address given here is The first address in this network It has just been named IP address. The PCs will receive addresses automatically from the pool. Leave the IP address as Set a start address of See the set up window below. Link PC should automatically obtain an IP address from the router. Ping PC2 from PC1. Ping should succeed.

It should be successful. That was pretty easy! If this a was a production network, this would mean an obvious security threat since this makes the network accessible to unauthorized users.

How to configure web server in cisco packet tracer - have

Configuration of mail server on cisco packet tracer Configuration of mail server on cisco packet tracer 1. In this tutorial we will learn how to set mail server on cisco packet tracer. It is required to keep IP in same network because here is connected network by single switch. There is no layer 3 device and VLAN. We assign IP to mail server Rest next IPs to each connected PC Create usernames and passwords. We provide same domain name and IP which we put on mail server.

After that click on add. Configuration of mail server on cisco packet tracer Configuration of mail server on cisco packet tracer 1. Its result comes on web page that appears on screen.

How to configure web server in cisco packet tracer - and have

How to create web how to configure web server in cisco packet tracer on packet tracer How to create web server on packet tracer 1. In this lesson we will learn about how to create first web page on cisco packet tracer that can be apply on real time web server. First let me clarify with you why do we create web page? What does it mean? What is for? When we search anything on Google, How to configure web server in cisco packet tracer, Mozila, safari or any web browser.

Its result comes on web page that appears on screen. So we are taking few PCs and one web server and one switch for connecting all devices. Make sure all devices should be connected by straight through cable because for connecting different devices, straight through cable is required. Assign IPs to each end device server and PCs of single network
