Hi am am trying to do the ccna skills 4 test, which includes:

frame relay
ppp
eigrp
dhcp
nat
pat
configure static routes.

Everything works fine until I get to NAT and PAT.

Here is the outline:
3 routers = ISP, Sydney, Auckland
ISP>Sydney  = Frame relay
Sydney> Auckland  = ppp with chap

regarding NAT the tasks are:
NAT to translate the 10.0  addresses to a 192.168.100.0/24. Use PAT to ensure that only the addresses 192.168.100.11 to .20 are translated to.
Use a static mapping of 10.10.0.1 to 192.168.0.1


my nat configs on ISP are

Interface e 0 = 10.10.0.1/16
ip nat inside
int s 0/0 = 192.168.2.1 /30
ip nat outside


access-list 1 permit 10.10.0.0 0.0.255.255
ip nat pool NAT 192.168.100.11 192.168.100.20 netmask 255.255.255.0
ip nat inside source static 10.10.0.1 192.168.100.1
ip nat inside source list 1 pool NAT overload

Sydney has a default route pointing back to ISP, which has also been redistributed to Auckkland.

Any ideas why the NAT dont work.
I cant see why

Thanks

Someone please explain this one to me

We're talking Arp, layer 2 here so surely we'd get a layer 2 broadcast storm whether PC2 was there or not.

Why does the explanation detail Unknown MAC unicast floods, PC1 is doing an arp, how's that unicast ?

Help... ???

Cheers, Rich

Hi all,

Do any of you find find subnetting hard? Have you spent money on simple solutions which simply don't deliver? Are you confuesd by too many books showing different ways to subnet or colleagues expressing their opinions? Do you need to write out charts just to find your subnet?

I honestly believe I have come up with the easiest technique to learn to subnet and I guarantee that it does not involve charts, videos or any other resources that are not allowed in the exam. This simply uses your head and some VERY BASIC arithmetic.

Please view the post at http://subnettingmadeeasy.blogspot.com

Cheers and happy subnetting!

In my second attempt I passed today with a 898. I used this site over 4 years ago to pass the 640-607 but ths 640-801 is much harder. The simulations on this site helped the most...especially the ACL and STP ones. I wished I had used this site prior to my first attempt but I did not think much had changed from the 640-607 but boy was I wrong. This site provides great on line realistick tests that will help you pass but better than that help you be a better Engineer. Make sure you can get 81% or better on all this sites on line practice tests and you should pass. I know the new test will be harder and the CCNP track is getting harder.

Hi,
I have come up to this question, not included here
            A
          1 2
          /  \
        1    1
        B2 -2C 

A is the root bridge and B2 is disabled
which ports are designated ports, choose three
A1
A2
B1
B2
C1
C2
with the exception of B2 all the rest are designated. Am I missing something?
Unless we don't consider root ports as designated ports.

Hi

It seems like the majority doesn't take this composite exam, but I personally don't like the drag of having multiple exams when you can kill them both in one shot. I passed my CCNA today, and it was no big deal to take it in one shot.

Can anybody share their experience or thoughts in regard of taking the composite 892 exam vs separate? Is it much harder?

Thanks

Hello,

    The N626 question asked you to configure one virtual connection. I thought that
line vty 0
login
Password cisco

but the choice was wrong.
Since vty allows five connection, starting at 0 and going until 4 (total 5), why was the answer

line vty 1
login
Password cisco

I know that this allows one connection also, but should you not start with 0 and not 1.

thank you

Any suggestions on what equipment to get for a decent VoIP lab, for CCVP and CCIE Voice?
Thanks.

anyone interested in voip i mean voice over ip

first my confusion is i think if there must be an internet also there must be
a computer over there . Is this true ?

and for voip: if we get to do voip in a company and we should have voip devices
in it then i want to communicate the analog phones between two branch offices
is it enough to have just voip gateways ?

another thing if we try to use voip phones what will change? can we use voip phones
without computer support ? i have seen somewhere "you can use voip phones
everywhere while travelling or... but how can it connect to the internet while
travelling?


last one is for dsl : i mean adsl ; while connecting from home to the internet
via dsl we use telephone line from isp and an internet cable for dsl and internet
ok then we use fast ethernet for modem to pc connecting.

if we want to do voip in a company across dsl how can we perform it ? do we
need a computer again?

schema :

analog phone - adc - voip device - router-modem - isp - modem-router - voip device-dac - analog phone is this right and where would be the dsl here?
