Ticket 4 – NAT ACL

May 3rd, 2018 Go to comments

Note: Although in our ticket we cannot ping the Web server from DSW1 (as the NAT configuration is wrong) but in the exam we can. This is a bug in the exam so be careful with it.

In this ticket we may see one of two cases below:

Case 1:

Configuration of R1

!
interface Serial0/0/1
ip address 209.65.200.225 255.255.255.252
ip nat outside
!
interface Serial0/0/0
ip address 10.1.1.1 255.255.255.252
ip nat outside
ip ospf message-digest-key 1 md5 TSHOOT
ip ospf authentication message-digest

Ans1) R1
Ans2) NAT
Ans3) Under interface Serial0/0/0 delete the ip nat outside command and add the ip nat inside command.

Case 2:

Configuration of R1

!
interface Serial0/0/1
ip address 209.65.200.225 255.255.255.252
ip nat inside
!
interface Serial0/0/0
ip address 10.1.1.1 255.255.255.252
ip nat inside
ip ospf message-digest-key 1 md5 TSHOOT
ip ospf authentication message-digest

Ans1) R1
Ans2) NAT
Ans3) Under interface Serial0/0/1 delete the ip nat inside command and add the ip nat outside command.
