Ticket 4 – NAT ACL

May 3rd, 2018 in TSHOOT v2 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.

    Selecting Ticket answers is enough @ exam – especially if you select the CORRECT answers! :D

    Do I have to allow FTP server can reach to internet too?

    permit 10.2.0.0 0.0.255.255 to support both FTP server and PC Clients
    or
    permit 10.2.1.0 0.0.0.255 to support only PC client

    As within most TSHOOT Tickets, it’s a matter of gaining just PC Client # 1 and 2 access to the @ (the external Web Server).
    Therefore, in principal this Ticket calls for just:
    permit 10.2.1.0 0.0.0.255 to support just PC client access to the @
    However correct “Cisco answer” for this Ticket @ test is considered to be:
    permit 10.2.0.0 0.0.255.255 which supports BOTH the FTP server AND the PC Clients at the same time.

    I labbed this question as explained by networktut using the 10.2.0.0 0.0.0.255 subnet, but still couldn’t ping.
    The i tried this option using the 10.2.0.0 0.255.0255:
    on R1#
    (conf t)# ip access-list standard Nat_Traffic
    R1(config-std-nacl)# permit 10.2.0.0 0.0.255.255

    It worked and i can ping from client1 to the webserver.

    Correct answer is on
    R1#
    (conf t)# ip access-list standard Nat_Traffic
    R1(config-std-nacl)# permit 10.2.0.0 0.0.255.255

    Yop Whiz Whiz:

    But the mentioned solution @ top of this page ALSO Works:

    add to acl 1 permit ip 10.2.1.0 0.0.0.255 !!!

    You need to open your eyes, in order to notice, that the THIRD OCTET (0) within the your mentioned (NOT pingable) statement above:

    permit 10.2.0.0 0.0.0.255

    doesn’t match the THIRD OCTET (1) within our Client 1 IP address: (10.2.1.3 255.255.255.0) and because of that, our poor client can’t ping anything outside the local TSHOOT infrastructure!

    However, if you use:

    permit ip 10.2.1.0 0.0.0.255 within the ACL – It works just so cool – right bro!?

    Hi guys,

    just cleared 960 thank you every one.

    DOES ANYBODY KNOW A SITE LIKE THIS FOR MCSE.

  9. Whiz Whiz

    Hi Rebeccca, you should check with examcollection dot com. That’s a very helpful website with valid dumbs.
    I took MSCA and MSCE cert exams last year 2013 and passed. Dumps from examcollection are very helpful. But you also need to read and not depend solely on dumbs. MCSE just like MCSA do not have Labs, just multiple choice questions including a few drag and drops.

    Hope that helps.

    Hi,

    Any one can help me, how to identify the question whether it is L2 or L3

  13. Mike
    December 9th, 2014

    1)
    Identify if it’s a L2 Type question @ exam = Learn to master the CCNP Switching stuff and in addition some CCNA based Network fundamentals stuff.

    2)
    Identify if it’s a L3 Type question @ exam = Learn to master the CCNP Routing stuff.

    There’s most likely no easy shortcuts in order to learn theese prerequisite networking topics, when prepareing for the TSHOOT exam.

    guys need a bit of help….
    they say there will be 45 questions
    and 13 trouble tickets
    each trouble ticket contains 3 questions
    so does that means 13 trouble tickets = 39 questions?
    13*3=39

  17. arxon

    @kanad

    1.When they say 45 question sthey mean around 45 in total (not exact number)
    2.Yes you are correct 13*3 =39 , few MCQ questions maybe with few DDs.

    Just follow khattak strategy to solve the tickes and you will be ok

    P.S giving my exam in 2 days

    Jai Shree Ram!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    Finally clear Tshoot with 1000/1000 and completed CCNP…………………
    2xMCQ, 1xDD and 13 TTs except DHCP helper and wrong eigrp AS.
    It was so nervousness before exam but while attempting feel quit better.
    Thanks to all guys who advised. Lot of thanks for Networktut team, you guys are rock.
    Just read and memorize Khatak strategy and go ahead. Even With khatak strategy you can complete the exam within 30 mnts by running “ipconfig and ping” command at clients.

    It’s so easy…..best of luck for all who are going for exam.

    Hi network tut
    can we use Tracert or traceroute on real exam ?

    So, how come we can ping from ASW1 and ASW2? It seems they are not using 10.1.0.0, they are using vlan 200, and yet the ping is successful?

    @Mohammad
    you can’t, you should do it from DSW1

    So, how do you solve Ticket 4? (without looking up answer) This one really stumped me.

  30. bs
    August 2nd, 2015

    @Tank:

    You could try Solving TT4 e.g. like this:

    First we’ll check connectivity on Client 1 towards the external web server:

    ping 209.65.200.241 :-(
    ping 209.65.200.225 :-(
    ping 10.1.1.1 :-))

    OK, now let’s move to R1 to see what’s going on there:

    R1#show ip route bgp
    B 209.65.200.240/29 [20/0] via 209.65.200.226, 00:01:34 – looks good :-))

    R1#sh ip route 10.2.1.0
    Routing entry for 10.2.1.0/24
    Known via “ospf 1”, distance 110, metric 213, type intra area
    Last update from 10.1.1.2 on Serial0/0/0.12, 00:01:31 ago
    Routing Descriptor Blocks:
    * 10.1.1.2, from 2.2.2.2, 00:01:31 ago, via Serial0/0/0.12 – Also fine! :-))
    Route metric is 213, traffic share count is 1

    OK, Now let’s check if the NAT works ok on R1:

    R1#show ip nat translations

    Oupps, it seems there’s NO 10.1.2.0 to 209.65.200.xxx (overload) Translations here :-(

    Therefore let’s check if the NAT ACL on R1 is ok?

    R1#sh acc Nat_Traffic
    Standard IP access list Nat_Traffic
    permit 10.1.0.0 0.0.255.255 (10 match(es))

    Hmm – Also here there’s NO user IP prefix: 10.2.1.0 permit entry within our Nat_Traffic std ACL :-(

    (Let’s double check this within R1 running-config, to be quite sure about this) –

    So here we notice, that we need to:

    Add the command: “permit 10.2.0.0 0.0.255.255 to the Nat_Traffic std access-list on R1

    to solve the TT4 NAT Problem.

    Hope this helps –
