    ip address 192.168.12.1 255.255.255.0

    !

    interface fastethernet1/0

    ip address 2.2.2.2 255.255.255.0

    ip access-group 101 in

    ip access-group 101 out

    !

    ip route 0.0.0.0 0.0.0.0 fastethernet1/0 2.2.2.1

    !

    access-list 101 permit tcp 192.168.12.0 0.0.0.255 any eq telnet

    access-list 101 deny icmp 192.168.12.0 0.0.0.255 any

    access-list 101 deny ip 2.2.2.0 0.0.0.255 any
