[CCNAv6 S2] 9.2.2.5 Packet Tracer - Configuring Dynamic NAT



Packet Tracer – Configuring Dynamic NAT
Objectives

Part 1: Configure Dynamic NAT

Part 2: Verify NAT Implementation

Part 1:     Configure Dynamic NAT
Step 1:     Configure traffic that will be permitted.

On R2, configure one statement for ACL 1 to permit any address belonging to 172.16.0.0/16.

Step 2:     Configure a pool of address for NAT.

Configure R2 with a NAT pool that uses all four addresses in the 209.165.76.196/30 address space.

Notice in the topology there are 3 network ranges that would be translated based on the ACL created. What will happen if more than 2 devices attempt to access the Internet?

Step 3:     Associate ACL1 with the NAT pool.

Step 4:     Configure the NAT interfaces.

Configure R2 interfaces with the appropriate inside and outside NAT commands.

Part 2:     Verify NAT Implementation
Step 1:     Access services across the Internet.

From the web browser of L1, PC1, or PC2, access the web page for Server1.

Step 2:     View NAT translations.

View the NAT translations on R2.

R2# show ip nat translations



Configuration R2:

[CCNAv6 S4] 8.2.4.14 Packet Tracer - Troubleshooting Enterprise Networks 3

Hình ảnh
Packet Tracer – Troubleshooting Enterprise Networks 3 Addressing Table Background This activity uses a variety of technologies you have encountered during your CCNA studies, including routing, port security, EtherChannel, DHCP, NAT, PPP, and Frame Relay. Your task is to review the requirements, isolate and resolve any issues, and then document the steps you took to verify the requirements. Note: This activity begins with a partial score. Requirements DHCP ·         R1 is the DHCP server for the R1 LAN. Switching Technologies ·         Port security is configured to only allow PC1 to access S1's F0/3 interface. All violations should disable the interface. ·         Link aggregation using EtherChannel is configured on S2, S3, and S4. Routing ·         All routers are configured with OSPF process ID 1 and no routing updates should be sent across interfaces that do n...

[CCNAv6 S2] 2.2.2.4 Packet Tracer - Configuring IPv4 Static and Default Routes

Hình ảnh
Packet Tracer - Configuring IPv4 Static and Default Routes Addressing Table Objectives Part 1: Examine the Network and Evaluate the Need for Static Routing Part 2: Configure Static and Default Routes Part 3: Verify Connectivity Background In this activity, you will configure static and default routes. A static route is a route that is entered manually by the network administrator to create a reliable and safe route. There are four different static routes that are used in this activity: a recursive static route, a directly attached static route, a fully specified static route, and a default route. Part 1:     Examine the Network and Evaluate the Need for Static Routing a.     Looking at the topology diagram, how many networks are there in total? b.    How many networks are directly connected to R1, R2, and R3? c.     How many static routes are required by each router to reach networks that are not directly ...

Packet Tracer – Troubleshooting Standard IPv4 ACLs Addressing Table Objectives Part 1: Troubleshoot ACL Issue 1 Part 2: Troubleshoot ACL Issue 2 Part 3: Troubleshoot ACL Issue 3 Scenario This network is meant to have the following three policies implemented: ·         Hosts from the 192.168.0.0/24 network are unable to access network 10.0.0.0/8. ·         L3 can’t access any devices in network 192.168.0.0/24. ·         L3 can’t access Server1 or Server2. L3 should only access Server3. ·         Hosts from the 172.16.0.0/16 network have full access to Server1, Server2 and Server3. Note: All FTP usernames and passwords are “cisco”. No other restrictions should be in place. Unfortunately, the rules that have been implemented are not working correctly. Your task is to find and fix the errors related to the access lists on R1. Part 1:     Troublesh...
