Lab 8.2.1 planning for access lists and port filters

Step 1: Restrict Client A to one subnet

You are asked to restrict client A to only the subnet to which it is currently attached. Client A needs to be able to access server A. but it does not need to accsess the internet or server B. where would you place the access list?

Router	Interface	Allow or Deny?	Input or output filter?	Why?
Router 2	0/0 dan 0/1	deny	input	Karena hanya untuk mengekses server yang berada di internal jaringan dan tidak bisa untuk eksternal jaringan atau jaringan luar

Step 2: Restrict client A access to server A but allow access to server B the internet

You are asked to restrict client B from accessing server B needs internet access and access to server B. where would you place the access list?

Router	Interface	Allow or Derry?	Input or output filter?	Why?
Router 1 dan 3	0/0 dan 0/1	allow	output	Karena diizinkan untu mengakses jaringan internal dan eksternal

Step 3: Allow only client A to access the routers using only SSH

You have been asked to secure access to the routers for only client A. which will be the management PC for those routers. You want to limit access to only SSH from Client A and prevent telnet access. Where would you place the access list?

Router	Interface	Input or output filter?	Port	Allow or Deny?	Why?
Router 1	0/0 dan 0/1	input	0	deny	Jaringan internal
Router 2	0/0 dan 0/1	output	0	allow	Jaringan eksternal
Router3	0/0 dan 0/1	output	0	allow	Jaringan eksternal
