Acl's on switches.

I have 5 subnets from my ISP.  I want to use a switch for routing 2960 or sf300-24p.  I just want to route one inside network to one outside subnet.  A point of sale system is setup on one static IP this VLAN would just need to conect to the one subnet on the outside.  If I turn on IP routing and create SVI's This will route between all subnets.  I also have a public emplolyee and management vlan.   They are on seperate static IP addresses. 

The three local networks will use private ip addressing.  How do I trananslate between the local private IP addresses and the designated address from the service providor.

An example I want 192.168.1.0 network in vlan 100 to route to only isp address 1

192.168.2.0 Vlan 200 to route only isp address 2

192.168.3.0 vlan 300 to route only to isp address 3

The issue is I cant have vlan 200 or vlan 300 comunicate with isp address 1 or vlan 100.

How can I do this with a catlyst 2960 with lanbase firmware. 

Thanks

Re: Acl's on switches.

Switches don't route. You need a router and it sounds like you need NAT configured.

Technically true but some of the better switch models such as the 3750X series are more than capable of Routing.

His 2960 may be able to do this if he has the right IOS as mentioned by Leo below.

Are you sure these are the only things you want to route? 

If yes, then a 2960 can do limited static routes if you upgrade to 12.2(55)SE2 and later.  You can enable routing if you change the SDM template to route.
