EWAN NAT/ACL PT Practice SBA
In this practice Packet Tracer Skills Exam, you are expected to:· Finish designing the IP addressing scheme.· Implement the addressing in the network to meet the stated requirements.· Configure and verify a DHCP server implementation.· Configure and verify WAN technologies.· Configure EIGRP to enable communication with the rest of the network.· Configure NAT totranslate addresses for traffic destined to the Internet.· Implement access control lists as part of a security policy.

Step 1: Finish the IP Addressing Design and Implementation.
Design an addressing scheme and fill in the Addressing Table based on the followingrequirements:a. Subnet the address space 172.16.1.128/25 to provide 50 host addresses for the R3 LAN whilewasting the fewest addresses.b. Assign the first available subnet to the R3 LAN.c. Assign the first (lowest) address in this subnet to the Fa0/0 interface on R3.d. Subnet the remaining address space to provide 30 host addresses for the R1 LAN whilewasting the fewest addresses.e. Assign the next availablesubnet to the R1 LAN.f. Assign the first (lowest) address in this subnet to the Fa0/0 interface on R1.g. Assign the last (highest) host address in this subnet to PC1.h. Finish the IP addressing configuration:· Configure R1 and R3 LAN interfaces with IP addressing.· Configure PC1 with IP addressing. PC3 will get its address from the DHCP server on R3 inthe next step.
Step 2: Configure and Verify R3as the DHCP Server.
a. Configure R3 as the DHCP server for the LAN attached to Fa0/0 using the followingguidelines:· Use the case-sensitive DHCP pool name of R3_LAN.· Exclude the first three host addresses in the subnet.b. Verify that PC3 now has full IP addressing. It may be necessary to toggle between “Static”and “DHCP” on the IP Configuration screen for PC3 before PC3 will send a DHCPrequest. PC3should be able to ping the default gateway.
Step 3: Configure WAN Technologies.
a. The link between R3 and R2 uses PPP with CHAP. The password is ciscochap. Verify thatR3 and R2 can ping each other.b. The link between R3 and R1 uses HDLC. R3 should be able to ping the other side of the link.Verify that R3 and R1 can ping each other.c. The link between R1 and R2 uses point-to-point FrameRelay subinterfaces. Verify that R1and R2 can ping each other.
Step 4: Configure and Verify EIGRP Routing.
a. Configure EIGRP routing on R1, R2, and R3.· Use AS number 100.



· Do not use the wildcard mask argument.· Do not advertise the network between R2 and the Internet.b. Configure R2 with a default route using the outbound interface argument. Use one commandto propagate the default routeinto the EIGRP routing process.c. Verify PC1 and PC3 can ping each other as well as R1, R2 and R3. You will not be able toping Internet hosts yet.
Step 5: Configure R2 with a NAT.
a. Configure NAT on R2 using the following guidelines:· Only addresses in the 172.16.1.128/25 address space will be translated.· Use the number 1 for the access list.· Configure PAT on the R2 S0/1/0 interface.b. Verifythat PC1 and PC3 can ping the Internet hosts.
Step 6: Configure Access Control Lists to Satisfy a Security Policy.
a. Configure and apply an ACL with the number 50 that implements the following policy:· Deny any host from the R3 LAN from accessing hosts on the R1 LAN.· Hosts on the R3 LAN should be able to ping any other destination.b. Verify that ACL 50 is operating as intended.c. Configure...
