Q150. CORRECT TEXT - (Topic 7) 

Answer: Select the console on Corp1 router Configuring ACL Corp1>enable Corp1#configure terminal comment: To permit only Host C (192.168.33.3){source addr} to access finance server address (172.22.242.23) {destination addr} on port number 80 (web) Corp1(config)#access-list 100 permit tcp host 192.168.33.3 host 172.22.242.23 eq 80 comment: To deny any source to access finance server address (172.22.242.23) {destination addr} on port number 80 (web) Corp1(config)#access-list 100 deny tcp any host 172.22.242.23 eq 80 comment: To permit ip protocol from any source to access any destination because of the implicit deny any any statement at the end of ACL. Corp1(config)#access-list 100 permit ip any any Applying the ACL on the Interface comment: Check show ip interface brief command to identify the interface type and number by checking the IP address configured. Corp1(config)#interface fa 0/1 If the ip address configured already is incorrect as well as the subnet mask. this should be corrected in order ACL to work type this commands at interface mode : no ip address 192.x.x.x 255.x.x.x (removes incorrect configured ipaddress and subnet mask) Configure Correct IP Address and subnet mask : ip address 172.22.242.30 255.255.255.240 ( range of address specified going to server is given as 172.22.242.17 - 172.22.242.30 ) comment: Place the ACL to check for packets going outside the interface towards the finance web server. Corp1(config-if)#ip access-group 100 out Corp1(config-if)#end Important: To save your running config to startup before exit. Corp1#copy running-config startup-config Verifying the Configuration : Step1: show ip interface brief command identifies the interface on which to apply access list. Step2: Click on each host A,B,C & D . Host opens a web browser page , Select address box of the web browser and type the ip address of finance web server(172.22.242.23) to test whether it permits /deny access to the finance web Server . Step 3: Only Host C (192.168.33.3) has access to the server . If the other host can also access then maybe something went wrong in your configuration . check whether you configured correctly and in order. Step 4: If only Host C (192.168.33.3) can access the Finance Web Server you can click on NEXT button to successfully submit the ACL SIM.
