Question : NAT on the Cisco 3750 / 3560 L3 switches

Could you kindly help me with the following questions:

1) Is there any flavour of the Cisco IOS on the 3750 or 3560 L3 switches that can do NAT ?

2) We are planning to replace an existing Linux machine running a huge number of iptables NAT rules and static routes with a suitable Cisco device (preferably a Layer3 switch).Is this a good idea ? Is this even feasible ? If not, what are the other options    
available ?

Please advise.

Cheers

Answer : NAT on the Cisco 3750 / 3560 L3 switches

I would call Cicso or a trusted reseller in your area.  I don't beleive that either of these support NAT.  In fact I don't think that Cicso has NAT in any of their layer 3 switches.  The "exception" is the Cat 6500, with a firewall module in it, it (really the firewall module) can do NAT.

Now, I would assume that you are really using the Linux machine as a router/firewall and not a "layer 3 switch.  Yes a layer 3 switch is like a router, but it is not.  I would also assume that you don't 24 or 48 Ethernet NIC is it.

So, I would look at how many ports you really need and then look at some Cicso routers that do support NAT.
