access list help

hi
if i have 4 switch 2950 each two switch connect to distrbution
switch (layer 3 switch using to routing ) then the two
distrbution switch connect to core switch then to pix 525 then
to router 2800 each switch contain 2 vlan (vlan 14 and vlan 10)
i use routing rip in pix
how i can prevent user of vlan 14 from enter to vlan 10 and user
of vlan 10 from enter to vlan 14 (mean i want the user on each VLAN not to be able to see the shearing file on other vlan)
exept ip 172.16.14.20
and 172.16.10.20
network for switch is
172.16.14.0
172.16.10.0

thanks

On your layer3 switch put below acces-list on your default vlan. (Assuming your layer 3 route traffic between 4 2950 switches)

access-list 101 permit host 172.16.14.20 any
access-list 101 permit host 172.16.10.20 any
access-list 101 deny ip 172.16.14.0 172.16.10.0
access-list 101 deny ip 172.16.10.0 172.16.14.0
access-list permit ip any any
