Hello im a beginner in using cisco so my task is admin can ping admin but student cant ping admin.
student1(198.140.70.4 255.255.255.248) and student 2 (198.140.70.11 255.255.255.248)
admin1(198.140.70.3 255.255.255.248 ) and admin2(198.140.70.10 255.255.255.248 ) .
 the router to router is using serial, se0/0/0 to se0/0/0 
switch1 connected to router1 is g0/0/0
the switch2 connected to router2 is g0/0/0
the problem i face is student 1 cant ping admin2 but still can ping admin1 . the same goes for student 2 which is cant ping admin1 but can ping admin2. i cant figure out how to block the ping i already use acl for both

which is 
Router1(config)# access-list 101 deny icmp host 198.140.70.4 host 198.140.70.3 echo
Router1(config)# access-list 101 deny icmp host 198.140.70.4 host 198.140.70.10 echo
Router1(config)# access-list 101 permit ip any any
Router1(config)# interface GigabitEthernet0/0
Router1(config-if)# ip access-group 101 in

Router2(config)# access-list 101 deny icmp host 198.140.70.11 host 198.140.70.3 echo
Router2(config)# access-list 101 deny icmp host 198.140.70.11 host 198.140.70.10 echo

Router2(config)# access-list 101 permit ip any any

Router2(config)# interface GigabitEthernet0/0

Router2(config-if)# ip access-group 101 in

Hello,

this is going to be tricky, as the hosts are both in the same subnet. Typically you would use VACL (Vlan Access Lists), but those are not supported in Packet Tracer. Maybe you can use the firewall available on the PCs (see screenshot attached)...
