To prevent the PC from accessing the IP network, create and apply an ACL to the ingress interface on the Layer 2 switch. This ACL permits only traffic sent to an IP address of 255.255.255.255 or 20.0.0.1 and to a UDP port of 43440.
Switch(config)#
Switch(config)#
Switch(config)# end
Switch# show
10 permit udp any any eq 43440
20 permit udp any 20.0.0.1 0.0.0.0 eq 43440
Note When you are creating an ACL, remember that, by default, the end of the access list contains an implicit deny statement for all packets if it did not find a match before reaching the end.
