ну межсетевого экрана в Cisco Packet Tracer нет:

access-list 100 deny ip any 192.168.0.0 0.0.3.255
access-list 100 permit ip any any

access-list 104 permit tcp 192.168.0.0 0.0.3.255 host 192.168.4.2 eq ftp
access-list 104 permit ip host 192.168.10.4 host 192.168.4.2

на каждый VLAN (192.168.0.1 до 192.168.3.0)
ip access-group 100 in

и на выход к FTP
ip access-group 104 out

Extended IP access list 110
10 permit ip host 12.0.0.4 host 11.0.0.4
20 permit ip host 12.0.0.5 host 11.0.0.2
30 permit ip host 13.0.0.5 host 11.0.0.2

70 permit ip host 14.0.0.2 host 11.0.0.5
80 deny ip any any
-----------------------------
interface FastEthernet0/0
ip address 11.0.0.1 255.0.0.0
ip access-group 110 out

и далее по всем 4-ем сеткам
