$4\mathrm{.}2$ Task $2$: Access Control Lists $(5$ marks$)$

You will need to work out which interface on which router this needs to be applied to$.$ Each

ACL must work and be seen to work. You must select one from the following, based on your

birth month:

If you are born in January, February or March $-$ you must stop any IP address from

$10\mathrm{.}0\mathrm{.}0\mathrm{.}0$ to $10\mathrm{.}0\mathrm{.}0\mathrm{.}127$ from pinging $123\mathrm{.}123\mathrm{.}123\mathrm{.}123-$ yet allow all other addresses

If you are born in April or May, you must stop any IP address from $10\mathrm{.}0\mathrm{.}0\mathrm{.}128$ to

$10\mathrm{.}0\mathrm{.}0\mathrm{.}254$ from pinging $123\mathrm{.}123\mathrm{.}123\mathrm{.}123-$ yet allow all other addresses

If you are born in June or July, you must stop any IP address from $10\mathrm{.}0\mathrm{.}0\mathrm{.}32$ to

$10\mathrm{.}0\mathrm{.}0\mathrm{.}127$ from pinging $123\mathrm{.}123\mathrm{.}123\mathrm{.}123-$ yet allow all other addresses

If you are born in August or September, you must stop any IP address from $10\mathrm{.}0\mathrm{.}0\mathrm{.}128$

to $10\mathrm{.}0\mathrm{.}0.191$ from pinging $123\mathrm{.}123\mathrm{.}123\mathrm{.}123-$ yet allow all other addresses

If you are born in October, November or December, you must stop any IP address from

$10\mathrm{.}0\mathrm{.}0\mathrm{.}64$ to $10\mathrm{.}0\mathrm{.}0\mathrm{.}127$ from pinging $123\mathrm{.}123\mathrm{.}123\mathrm{.}123-$ yet allow all other addresses

NOTE: Please be aware that the ACL must NOT restrict any other traffic.

Marks will be allocated for:

Creating an ACL that meets the above 'selected' criteria

$(4$ marks$)$

Proving that a change of IP address, other than those allocated to the PC$\text{'}$s also

demonstrates the operation of the ACL. Also prove that you are still able to ping to

$99\mathrm{.}0\mathrm{.}0.2$ irrespective of device IP address.
