Access List - Configurazione Extended ACL tramite CISCO Packet Tracer
Assume that we want to DENY all traffic from 192.168.2.102 wherever
With using the Extended ACL we are "closest to the source" and this means that we need to work on:
R1 (closest to the source)
Gig0/1 on R0 (closest to the source) inbound
R1(config)#ip access-list extended 100
R1(config-ext-nacl)#deny icmp host 192.168.2.102 any
R1(config-ext-nacl)#permit icmp any any
R1(config-ext-nacl)#exit
R1(config)#int g0/1
R1(config-if)#ip access-group 100 in
