    Configuring NAT

    Objective Use Packet Tracer to practice the following skills: Completing router configuration. Configure a router to use network address translation (NAT) to convert internal IP addresses into outside public IP addresses. Scenario An ISP has allocated a company the public classless interdomain routing (CIDR) IP address This is equivalent to 2 public IP addresses. Since the company has an internal requirement for more than 2 addresses, the IT manager has decided to implement NAT with overload. Routing will be done between the ISP and the gateway router used by the company. A static route will be used between the ISP and gateway routers and a default route will be used between the gateway router and the ISP. The ISP connection to the Internet will be represented by a loopback address on the ISP router. . Required Files To complete this lab, the following files will be needed: Configuring NAT.pka Configuring NAT LabHandout.doc Activity: Step 1 Open the PT activity file, Configuring NAT.pka. Using the CLI, configure the routers with the following IP addresses: (Set the clock rate to 56000 on the appropriate interfaces.) ISP Serial 0/0 /30 Gateway Serial 0/0 /30 Gateway FastEthernet 0/0 /24 Configure the hosts as follows: PC0 /24 PC1 /24 Step 2 Create a static route from the ISP to the Gateway router. Addresses in the space have been allocated for Internet access. Use the ip route command to create the static route. Step 3 Create a default route from the Gateway router to the ISP router. This will forward any unknown destination address traffic to the ISP by setting a Gateway of Last Resort on the Gateway router. Try to reach all addresses using ping from one of the hosts. The host will not be able to successfully ping the ISP Serial interface. Why does this ping fail? ___________________________________________________________________________ ________________________________________________________________________ Step 4 On the Gateway router define the pool of public addresses, use the ip nat pool command, name it "public-access" and assign the useable addresses for the pool /30. Step 5 Define a standard access list (use "1" as the ACL number) that will define the hosts needing address translation. Step 6 Define the NAT translation from inside list to outside pool (overload the interface). Step 7 Specify the NAT interfaces on the Gateway router. Step 8 Test the configuration. The hosts should now be able to successfully ping all the interfaces on each router.
  3. Hi are you trying to monitor the traffic? Performance? Try this site i hope this can help you. http://www.techrepublic.com/article/analyze-traffic-on-switch-ports-with-span-and-rspan/6153401 Thanks
  4. Give a person a fish and you feed them for a day; teach that person to use the Internet and they won't bother you for weeks.
